# 🤗 Optimum Intel

🤗 Optimum Intel is the interface between the 🤗 Transformers and Diffusers libraries and the different tools and libraries provided by Intel to accelerate end-to-end pipelines on Intel architectures.

[Intel Neural Compressor](https://www.intel.com/content/www/us/en/developer/tools/oneapi/neural-compressor.html) is an open-source library enabling the usage of the most popular compression techniques such as quantization, pruning and knowledge distillation. It supports automatic accuracy-driven tuning strategies in order for users to easily generate quantized model. The users can easily apply static, dynamic and aware-training quantization approaches while giving an expected accuracy criteria. It also supports different weight pruning techniques enabling the creation of pruned model giving a predefined sparsity target.

[OpenVINO](https://docs.openvino.ai) is an open-source toolkit that enables high performance inference capabilities for Intel CPUs, GPUs, and special DL inference accelerators ([see](https://docs.openvino.ai/2024/about-openvino/compatibility-and-support/supported-devices.html) the full list of supported devices). It is supplied with a set of tools to optimize your models with compression techniques such as quantization, pruning and knowledge distillation. Optimum Intel provides a simple interface to optimize your Transformers and Diffusers models, convert them to the OpenVINO Intermediate Representation (IR) format and run inference using OpenVINO Runtime.

[Intel Extension for PyTorch](https://intel.github.io/intel-extension-for-pytorch/#introduction) (IPEX) is an open-source library which provides optimizations for both eager mode and graph mode, however, compared to eager mode, graph mode in PyTorch* normally yields better performance from optimization techniques, such as operation fusion.

### Distributed training
https://huggingface.co/docs/optimum.intel/v1.26.0/neural_compressor/distributed_training.md

# Distributed training

When training on a single CPU is too slow, we can use multiple CPUs. This guide focuses on PyTorch-based DDP enabling distributed CPU training efficiently.

Distributed training on multiple CPUs is launched by mpirun which supports both Gloo and oneCCL as collective communication backends. And for performance seek, Intel recommends to use oneCCL backend.

[Intel® oneCCL](https://github.com/oneapi-src/oneCCL) (collective communications library) is a library for efficient distributed deep learning training implementing such collectives like allreduce, allgather, alltoall. For more information on oneCCL, please refer to the [oneCCL documentation](https://spec.oneapi.com/versions/latest/elements/oneCCL/source/index.html) and [oneCCL specification](https://spec.oneapi.com/versions/latest/elements/oneCCL/source/index.html).

Module `oneccl_bindings_for_pytorch` (`torch_ccl` before version 1.12)  implements PyTorch C10D ProcessGroup API and can be dynamically loaded as external ProcessGroup and only works on Linux platform now

Check more detailed information for [oneccl_bind_pt](https://github.com/intel/torch-ccl).

We will show how to use oneCCL backend-ed distributed training as below steps.

Intel® oneCCL Bindings for PyTorch installation:

Wheel files are available for the following Python versions:

| Extension Version | Python 3.6 | Python 3.7 | Python 3.8 | Python 3.9 | Python 3.10 |
| :---------------: | :--------: | :--------: | :--------: | :--------: | :---------: |
| 1.12.1            |            | √          | √          | √          | √           |
| 1.12.0            |            | √          | √          | √          | √           |
| 1.11.0            |            | √          | √          | √          | √           |
| 1.10.0            | √          | √          | √          | √          |             |

```
pip install oneccl_bind_pt=={pytorch_version} -f https://software.intel.com/ipex-whl-stable
```
where `{pytorch_version}` should be your PyTorch version, for instance 1.12.0.
Versions of oneCCL and PyTorch must match.

PyTorch 1.12.1 should work with `oneccl_bindings_for_pytorch` 1.12.1

MPI tool set for Intel® oneCCL 1.12.0

```

The following command enables training with 2 processes on one node, with one process running per one socket. The variables OMP_NUM_THREADS/CCL_WORKER_COUNT can be tuned for optimal performance.
```shell script
export CCL_WORKER_COUNT=1
export MASTER_ADDR=127.0.0.1
mpirun -n 2 -genv OMP_NUM_THREADS=23 \
python3 run_qa.py \
    --model_name_or_path distilbert-base-uncased-distilled-squad \
    --dataset_name squad \
    --apply_quantization \
    --quantization_approach static \
    --do_train \
    --do_eval \
    --verify_loading \
    --output_dir /tmp/squad_output \
    --no_cuda \
    --xpu_backend ccl
```

The following command enables training with a total of four processes on two nodes (node0 and node1, taking node0 as the main process), ppn (processes per node) is set to 2, with one process running per one socket. The variables OMP_NUM_THREADS/CCL_WORKER_COUNT can be tuned for optimal performance.

In node0, you need to create a configuration file which contains the IP addresses of each node (for example hostfile) and pass that configuration file path as an argument.
```shell script
 cat hostfile
 xxx.xxx.xxx.xxx #node0 ip
 xxx.xxx.xxx.xxx #node1 ip
```
Now, run the following command in node0 and **4DDP** will be enabled in node0 and node1:
```shell script
export CCL_WORKER_COUNT=1
export MASTER_ADDR=xxx.xxx.xxx.xxx #node0 ip
mpirun -f hostfile -n 4 -ppn 2 \
-genv OMP_NUM_THREADS=23 \
python3 run_qa.py \
    --model_name_or_path distilbert-base-uncased-distilled-squad \
    --dataset_name squad \
    --apply_quantization \
    --quantization_approach static \
    --do_train \
    --do_eval \
    --verify_loading \
    --output_dir /tmp/squad_output \
    --no_cuda \
    --xpu_backend ccl
```

### Optimization
https://huggingface.co/docs/optimum.intel/v1.26.0/neural_compressor/optimization.md

# Optimization

Optimum Intel can be used to apply popular compression techniques such as quantization, pruning and knowledge distillation. 

## Post-training optimization

Post-training compression techniques such as dynamic and static quantization can be easily applied on your model using our [`INCQuantizer`](optimization).
Note that quantization is currently only supported for CPUs (only CPU backends are available), so we will not be utilizing GPUs / CUDA in the following examples.

### Dynamic quantization

You can easily add dynamic quantization on your model by using the following command line:

```bash
optimum-cli inc quantize --model distilbert-base-cased-distilled-squad --output quantized_distilbert
```

When applying post-training quantization, an accuracy tolerance along with an adapted evaluation function can also be specified in order to find a quantized model meeting the specified constraints. This can be done for both dynamic and static quantization.

```python
import evaluate
from optimum.intel import INCQuantizer
from datasets import load_dataset
from transformers import AutoModelForQuestionAnswering, AutoTokenizer, pipeline
from neural_compressor.config import AccuracyCriterion, TuningCriterion, PostTrainingQuantConfig

model_name = "distilbert-base-cased-distilled-squad"
model = AutoModelForQuestionAnswering.from_pretrained(model_name)
tokenizer = AutoTokenizer.from_pretrained(model_name)
eval_dataset = load_dataset("squad", split="validation").select(range(64))
task_evaluator = evaluate.evaluator("question-answering")
qa_pipeline = pipeline("question-answering", model=model, tokenizer=tokenizer)

def eval_fn(model):
    qa_pipeline.model = model
    metrics = task_evaluator.compute(model_or_pipeline=qa_pipeline, data=eval_dataset, metric="squad")
    return metrics["f1"]

# Set the accepted accuracy loss to 5%
accuracy_criterion = AccuracyCriterion(tolerable_loss=0.05)
# Set the maximum number of trials to 10
tuning_criterion = TuningCriterion(max_trials=10)
quantization_config = PostTrainingQuantConfig(
    approach="dynamic", accuracy_criterion=accuracy_criterion, tuning_criterion=tuning_criterion
)
quantizer = INCQuantizer.from_pretrained(model, eval_fn=eval_fn)
quantizer.quantize(quantization_config=quantization_config, save_directory="dynamic_quantization")
```

### Static quantization

In the same manner we can apply static quantization, for which we also need to generate the calibration dataset in order to perform the calibration step.

```python
from functools import partial
from transformers import AutoModelForSequenceClassification, AutoTokenizer
from neural_compressor.config import PostTrainingQuantConfig
from optimum.intel import INCQuantizer

model_name = "distilbert-base-uncased-finetuned-sst-2-english"
model = AutoModelForSequenceClassification.from_pretrained(model_name)
tokenizer = AutoTokenizer.from_pretrained(model_name)
# The directory where the quantized model will be saved
save_dir = "static_quantization"

def preprocess_function(examples, tokenizer):
    return tokenizer(examples["sentence"], padding="max_length", max_length=128, truncation=True)

# Load the quantization configuration detailing the quantization we wish to apply
quantization_config = PostTrainingQuantConfig(approach="static")
quantizer = INCQuantizer.from_pretrained(model)
# Generate the calibration dataset needed for the calibration step
calibration_dataset = quantizer.get_calibration_dataset(
    "glue",
    dataset_config_name="sst2",
    preprocess_function=partial(preprocess_function, tokenizer=tokenizer),
    num_samples=100,
    dataset_split="train",
)
quantizer = INCQuantizer.from_pretrained(model)
# Apply static quantization and save the resulting model
quantizer.quantize(
    quantization_config=quantization_config,
    calibration_dataset=calibration_dataset,
    save_directory=save_dir,
)
```

### Specify Quantization Recipes

The [SmoothQuant](https://arxiv.org/abs/2211.10438) methodology is available for post-training quantization. This methodology usually improves the accuracy of the model in comparison to other post-training static quantization methodologies. This is done by migrating the difficulty from activations to weights with a mathematically equivalent transformation.
```diff
- quantization_config = PostTrainingQuantConfig(approach="static")
+ recipes={"smooth_quant": True,  "smooth_quant_args": {"alpha": 0.5, "folding": True}}
+ quantization_config = PostTrainingQuantConfig(approach="static", backend="ipex", recipes=recipes)
```
Please refer to INC [documentation](https://github.com/intel/neural-compressor/blob/master/docs/source/smooth_quant.md) and the list of [models](https://github.com/intel/neural-compressor/blob/master/docs/source/smooth_quant.md#validated-models) quantized with the methodology for more details. 


### Distributed Acuracy-aware Tuning
One challenge in model quantization is identifying the optimal configuration that balances accuracy and performance. Distributed tuning speeds up this time-consuming process by parallelizing it across multiple nodes, which accelerates the tuning process in linear scaling.

To utilize distributed tuning, please set the `quant_level` to `1` and run it with `mpirun`.


```diff
- quantization_config = PostTrainingQuantConfig(approach="static")
+ quantization_config = PostTrainingQuantConfig(approach="static", quant_level=1)
```

```shell
mpirun -np <number_of_processes> <RUN_CMD>
```

Please refer to INC [documentation](https://github.com/intel/neural-compressor/blob/master/docs/source/tuning_strategies.md#distributed-tuning) and [text-classification](https://github.com/huggingface/optimum-intel/tree/main/examples/neural_compressor/text-classification) example for more details. 


## During training optimization

The [`INCTrainer`](https://huggingface.co/docs/optimum/main/intel/reference_inc#optimum.intel.INCTrainer) class provides an API to train your model while combining different compression techniques such as knowledge distillation, pruning and quantization.
The `INCTrainer` is very similar to the 🤗 Transformers [`Trainer`](https://huggingface.co/docs/transformers/main/en/main_classes/trainer#trainer), which can be replaced with minimal changes in your code.

### Quantization

To apply quantization during training, you only need to create the appropriate configuration and pass it to the `INCTrainer`.

```diff
  import evaluate
  import numpy as np
  from datasets import load_dataset
  from transformers import AutoModelForSequenceClassification, AutoTokenizer, TrainingArguments, default_data_collator
- from transformers import Trainer
+ from optimum.intel import INCModelForSequenceClassification, INCTrainer
+ from neural_compressor import QuantizationAwareTrainingConfig

  model_id = "distilbert-base-uncased-finetuned-sst-2-english"
  model = AutoModelForSequenceClassification.from_pretrained(model_id)
  tokenizer = AutoTokenizer.from_pretrained(model_id)
  dataset = load_dataset("glue", "sst2")
  dataset = dataset.map(lambda examples: tokenizer(examples["sentence"], padding=True, max_length=128), batched=True)
  metric = evaluate.load("glue", "sst2")
  compute_metrics = lambda p: metric.compute(predictions=np.argmax(p.predictions, axis=1), references=p.label_ids)

  # The directory where the quantized model will be saved
  save_dir = "quantized_model"

  # The configuration detailing the quantization process
+ quantization_config = QuantizationAwareTrainingConfig()

- trainer = Trainer(
+ trainer = INCTrainer(
      model=model,
+     quantization_config=quantization_config,
      args=TrainingArguments(save_dir, num_train_epochs=1.0, do_train=True, do_eval=False),
      train_dataset=dataset["train"].select(range(300)),
      eval_dataset=dataset["validation"],
      compute_metrics=compute_metrics,
      tokenizer=tokenizer,
      data_collator=default_data_collator,
  )

  train_result = trainer.train()
  metrics = trainer.evaluate()
  trainer.save_model()

- model = AutoModelForSequenceClassification.from_pretrained(save_dir)
+ model = INCModelForSequenceClassification.from_pretrained(save_dir)
```

### Pruning

In the same manner, pruning can be applied by specifying the pruning configuration detailing the desired pruning process.
To know more about the different supported methodologies, you can refer to the Neural Compressor [documentation](https://github.com/intel/neural-compressor/tree/master/neural_compressor/compression/pruner#pruning-types).
At the moment, pruning is applied on both the linear and the convolutional layers, and not on other layers such as the embeddings. It's important to mention that the pruning sparsity defined in the configuration will be applied on these layers, and thus will not results in the global model sparsity.

```diff
- from transformers import Trainer
+ from optimum.intel import INCTrainer
+ from neural_compressor import WeightPruningConfig

  # The configuration detailing the pruning process
+ pruning_config = WeightPruningConfig(
+     pruning_type="magnitude",
+     start_step=0,
+     end_step=15,
+     target_sparsity=0.2,
+     pruning_scope="local",
+ )

- trainer = Trainer(
+ trainer = INCTrainer(
      model=model,
+     pruning_config=pruning_config,
      args=TrainingArguments(save_dir, num_train_epochs=1.0, do_train=True, do_eval=False),
      train_dataset=dataset["train"].select(range(300)),
      eval_dataset=dataset["validation"],
      compute_metrics=compute_metrics,
      tokenizer=tokenizer,
      data_collator=default_data_collator,
  )

  train_result = trainer.train()
  metrics = trainer.evaluate()
  trainer.save_model()

  model = AutoModelForSequenceClassification.from_pretrained(save_dir)
```
### Knowledge distillation

Knowledge distillation can also be applied in the same manner.
To know more about the different supported methodologies, you can refer to the Neural Compressor [documentation](https://github.com/intel/neural-compressor/blob/master/docs/source/distillation.md)

```diff
- from transformers import Trainer
+ from optimum.intel import INCTrainer
+ from neural_compressor import DistillationConfig

+ teacher_model_id = "textattack/bert-base-uncased-SST-2"
+ teacher_model = AutoModelForSequenceClassification.from_pretrained(teacher_model_id)
+ distillation_config = DistillationConfig(teacher_model=teacher_model)

- trainer = Trainer(
+ trainer = INCTrainer(
      model=model,
+     distillation_config=distillation_config,
      args=TrainingArguments(save_dir, num_train_epochs=1.0, do_train=True, do_eval=False),
      train_dataset=dataset["train"].select(range(300)),
      eval_dataset=dataset["validation"],
      compute_metrics=compute_metrics,
      tokenizer=tokenizer,
      data_collator=default_data_collator,
  )

  train_result = trainer.train()
  metrics = trainer.evaluate()
  trainer.save_model()

  model = AutoModelForSequenceClassification.from_pretrained(save_dir)
```

## Loading a quantized model

To load a quantized model hosted locally or on the 🤗 hub, you must instantiate you model using our [`INCModelForXxx`](reference) classes.

```python
from optimum.intel import INCModelForSequenceClassification

model_name = "Intel/distilbert-base-uncased-finetuned-sst-2-english-int8-dynamic"
model = INCModelForSequenceClassification.from_pretrained(model_name)
```

You can load many more quantized models hosted on the hub under the Intel organization [`here`](https://huggingface.co/Intel).

## Inference with Transformers pipeline

The quantized model can then easily be used to run inference with the Transformers [pipelines](https://huggingface.co/docs/transformers/main/en/main_classes/pipelines).

```python
from transformers import AutoTokenizer, pipeline

tokenizer = AutoTokenizer.from_pretrained(model_id)
pipe_cls = pipeline("text-classification", model=model, tokenizer=tokenizer)
text = "He's a dreadful magician."
outputs = pipe_cls(text)

[{'label': 'NEGATIVE', 'score': 0.9880216121673584}]
```

Check out the [`examples`](https://github.com/huggingface/optimum-intel/tree/main/examples) directory for more sophisticated usage.

  `past_key_values` is used, optionally only the last `decoder_input_ids` have to be input (see
  `past_key_values`).

  Default behavior: generate a tensor that ignores pad tokens in `decoder_input_ids`. Causal mask will also
  be used by default.
- **encoder_outputs** (`tuple(tuple(torch.FloatTensor)`, *optional*) --
  Tuple consists of (`last_hidden_state`, `optional`: *hidden_states*, `optional`: *attentions*)
  `last_hidden_state` of shape `(batch_size, sequence_length, hidden_size)` is a sequence of hidden states at
  the output of the last layer of the encoder. Used in the cross-attention of the decoder.

### Inference
https://huggingface.co/docs/optimum.intel/v1.26.0/openvino/inference.md

# Inference

Optimum Intel can be used to load optimized models from the [Hub](https://huggingface.co/models?library=openvino&sort=downloads) and create pipelines to run inference with OpenVINO Runtime on a variety of Intel processors ([see](https://docs.openvino.ai/2024/about-openvino/compatibility-and-support/supported-devices.html) the full list of supported devices)


## Loading

### Transformers models

Once [your model was exported](export), you can load it by replacing the `AutoModelForXxx` class with the corresponding `OVModelForXxx`.

```diff
- from transformers import AutoModelForCausalLM
+ from optimum.intel import OVModelForCausalLM
  from transformers import AutoTokenizer, pipeline

  model_id = "helenai/gpt2-ov"
- model = AutoModelForCausalLM.from_pretrained(model_id)
  # here the model was already exported so no need to set export=True
+ model = OVModelForCausalLM.from_pretrained(model_id)
  tokenizer = AutoTokenizer.from_pretrained(model_id)
  pipe = pipeline("text-generation", model=model, tokenizer=tokenizer)
  results = pipe("He's a dreadful magician and")
```

As shown in the table below, each task is associated with a class enabling to automatically load your model.

| Auto Class                           | Task                                 |
|--------------------------------------|--------------------------------------|
| `OVModelForSequenceClassification`   | `text-classification`                |
| `OVModelForTokenClassification`      | `token-classification`               |
| `OVModelForQuestionAnswering`        | `question-answering`                 |
| `OVModelForAudioClassification`      | `audio-classification`               |
| `OVModelForImageClassification`      | `image-classification`               |
| `OVModelForFeatureExtraction`        | `feature-extraction`                 |
| `OVModelForMaskedLM`                 | `fill-mask`                          |
| `OVModelForImageClassification`      | `image-classification`               |
| `OVModelForAudioClassification`      | `audio-classification`               |
| `OVModelForCausalLM`                 | `text-generation-with-past`          |
| `OVModelForSeq2SeqLM`                | `text2text-generation-with-past`     |
| `OVModelForSpeechSeq2Seq`            | `automatic-speech-recognition`       |
| `OVModelForVision2Seq`               | `image-to-text`                      |
| `OVModelForTextToSpeechSeq2Seq`      | `text-to-audio`                      |

### Diffusers models

Make sure you have 🤗 Diffusers installed. To install `diffusers`:

```bash
pip install diffusers
```

```diff
- from diffusers import StableDiffusionPipeline
+ from optimum.intel import OVStableDiffusionPipeline

  model_id = "echarlaix/stable-diffusion-v1-5-openvino"
- pipeline = StableDiffusionPipeline.from_pretrained(model_id)
+ pipeline = OVStableDiffusionPipeline.from_pretrained(model_id)
  prompt = "sailing ship in storm by Rembrandt"
  images = pipeline(prompt).images
```


As shown in the table below, each task is associated with a class enabling to automatically load your model.

| Auto Class                           | Task                                 |
|--------------------------------------|--------------------------------------|
| `OVStableDiffusionPipeline`          | `text-to-image`                      |
| `OVStableDiffusionImg2ImgPipeline`   | `image-to-image`                     |
| `OVStableDiffusionInpaintPipeline`   | `inpaint`                            |
| `OVStableDiffusionXLPipeline`        | `text-to-image`                      |
| `OVStableDiffusionXLImg2ImgPipeline` | `image-to-image`                     |
| `OVLatentConsistencyModelPipeline`   | `text-to-image`                      |
| `OVLTXPipeline`                      | `text-to-video`                      |
| `OVPipelineForText2Video`            | `text-to-video`                      |

See the [reference documentation](reference) for more information about parameters, and examples for different tasks.


## Compilation

By default the model will be compiled when instantiating an `OVModel`. In the case where the model is reshaped or placed to another device, the model will need to be recompiled again, which will happen by default before the first inference (thus inflating the latency of the first inference). To avoid an unnecessary compilation, you can disable the first compilation by setting `compile=False`.

```python
from optimum.intel import OVModelForQuestionAnswering

model_id = "distilbert/distilbert-base-cased-distilled-squad"
# Load the model and disable the model compilation
model = OVModelForQuestionAnswering.from_pretrained(model_id, compile=False)
```

To run inference on Intel integrated or discrete GPU, use `.to("gpu")`. On GPU, models run in FP16 precision by default. (See [OpenVINO documentation](https://docs.openvino.ai/2024/get-started/configurations/configurations-intel-gpu.html) about installing drivers for GPU inference).

```python
model.to("gpu")
```

The model can be compiled:

```python
model.compile()
```

## Static shape

By default, dynamic shapes are supported, enabling inference for inputs of every shape. To speed up inference, static shapes can be enabled by giving the desired input shapes with [.reshape()](reference#optimum.intel.OVBaseModel.reshape).

```python
# Fix the batch size to 1 and the sequence length to 40
batch_size, seq_len = 1, 40
model.reshape(batch_size, seq_len)
```

When fixing the shapes with the `reshape()` method, inference cannot be performed with an input of a different shape.

```python

from transformers import AutoTokenizer
from optimum.intel import OVModelForQuestionAnswering

model_id = "distilbert/distilbert-base-cased-distilled-squad"
model = OVModelForQuestionAnswering.from_pretrained(model_id, compile=False)
tokenizer = AutoTokenizer.from_pretrained(model_id)
batch_size, seq_len = 1, 40
model.reshape(batch_size, seq_len)
# Compile the model before the first inference
model.compile()

question = "Which name is also used to describe the Amazon rainforest ?"
context = "The Amazon rainforest, also known as Amazonia or the Amazon Jungle"
tokens = tokenizer(question, context, max_length=seq_len, padding="max_length", return_tensors="np")

outputs = model(**tokens)
```

For models that handle images, you can also specify the `height` and `width` when reshaping your model:

```python
batch_size, num_images, height, width = 1, 1, 512, 512
pipeline.reshape(batch_size=batch_size, height=height, width=width, num_images_per_prompt=num_images)
images = pipeline(prompt, height=height, width=width, num_images_per_prompt=num_images).images
```

## Configuration

The `ov_config` parameter allow to provide custom OpenVINO configuration values. This can be used for example to enable full precision inference on devices where FP16 or BF16 inference precision is used by default.

```python
ov_config = {"INFERENCE_PRECISION_HINT": "f32"}
model = OVModelForSequenceClassification.from_pretrained(model_id, ov_config=ov_config)
```

Optimum Intel leverages OpenVINO's model caching to speed up model compiling on GPU. By default a `model_cache` directory is created in the model's directory in the [Hugging Face Hub cache](https://huggingface.co/docs/huggingface_hub/main/en/guides/manage-cache). To override this, use the ov_config parameter and set `CACHE_DIR` to a different value. To disable model caching on GPU, set `CACHE_DIR` to an empty string.

```python
ov_config = {"CACHE_DIR": ""}
model = OVModelForSequenceClassification.from_pretrained(model_id, device="gpu", ov_config=ov_config)
```

## Weight quantization

You can also apply fp16, 8-bit or 4-bit weight compression on the Linear, Convolutional and Embedding layers when loading your model to reduce the memory footprint and inference latency.

For more information on the quantization parameters checkout the [documentation](optimization#weight-only-quantization).

<Tip warning={true}>

If not specified, `load_in_8bit` will be set to `True` by default when models larger than 1 billion parameters are exported to the OpenVINO format (with `export=True`). You can disable it with `load_in_8bit=False`.

</Tip>

It's also possible to apply quantization on both weights and activations using the [`OVQuantizer`](optimization#static-quantization).

### Export your model
https://huggingface.co/docs/optimum.intel/v1.26.0/openvino/export.md

# Export your model

To export a [model](https://huggingface.co/docs/optimum/main/en/intel/openvino/models) hosted on the [Hub](https://huggingface.co/models) you can use our [space](https://huggingface.co/spaces/echarlaix/openvino-export). After conversion, a repository will be pushed under your namespace, this repository can be either public or private.

## Using the CLI

To export your model to the [OpenVINO IR](https://docs.openvino.ai/2024/documentation/openvino-ir-format.html) format with the CLI :

```bash
optimum-cli export openvino --model meta-llama/Meta-Llama-3-8B ov_model/
```

To export a private model or a model that requires access, you can either run `huggingface-cli login` to log in permanently, or set the environment variable `HF_TOKEN` to a [token](https://huggingface.co/settings/tokens) with access to the model. See the [authentication documentation](https://huggingface.co/docs/huggingface_hub/quick-start#authentication) for more information.

The model argument can either be the model ID of a model hosted on the [Hub](https://huggingface.co/models) or a path to a model hosted locally. For local models, you need to specify the task for which the model should be loaded before export, among the list of the [supported tasks](https://huggingface.co/docs/optimum/main/en/exporters/task_manager).

```bash
optimum-cli export openvino --model local_llama --task text-generation-with-past ov_model/
```

                        'image-segmentation', 'inpainting', 'sentence-similarity', 'text-to-audio', 'image-to-text',
                        'automatic-speech-recognition', 'token-classification', 'text-to-image', 'audio-classification',
                        'feature-extraction', 'semantic-segmentation', 'masked-im', 'audio-xvector',
                        'audio-frame-classification', 'text2text-generation', 'multiple-choice', 'depth-estimation',
                        'image-classification', 'fill-mask', 'zero-shot-object-detection', 'object-detection',
                        'question-answering', 'zero-shot-image-classification', 'mask-generation', 'text-generation',
                        'text-classification']. For decoder models, use 'xxx-with-past' to export the model using past
                        key values in the decoder.
  --framework {pt}   The framework to use for the export. Defaults to 'pt' for PyTorch.
  --trust-remote-code   Allows to use custom code for the modeling hosted in the model repository. This option should
                        only be set for repositories you trust and in which you have read the code, as it will execute
                        on your local machine arbitrary code present in the model repository.
  --weight-format {fp32,fp16,int8,int4,mxfp4,nf4,cb4}
                        The weight format of the exported model. Option 'cb4' represents a codebook with 16
                        fixed fp8 values in E4M3 format.
  --quant-mode {int8,f8e4m3,f8e5m2,nf4_f8e4m3,nf4_f8e5m2,cb4_f8e4m3,int4_f8e4m3,int4_f8e5m2}
                        Quantization precision mode. This is used for applying full model quantization including
                        activations.
  --library {transformers,diffusers,timm,sentence_transformers,open_clip}
                        The library used to load the model before export. If not provided, will attempt to infer the
                        local checkpoint's library
  --cache_dir CACHE_DIR
                        The path to a directory in which the downloaded model should be cached if the standard cache
                        should not be used.
  --pad-token-id PAD_TOKEN_ID
                        This is needed by some models, for some tasks. If not provided, will attempt to use the
                        tokenizer to guess it.
  --ratio RATIO         A parameter used when applying 4-bit quantization to control the ratio between 4-bit and 8-bit
                        quantization. If set to 0.8, 80% of the layers will be quantized to int4 while 20% will be
                        quantized to int8. This helps to achieve better accuracy at the sacrifice of the model size
                        and inference latency. Default value is 1.0. Note: If dataset is provided, and the ratio is
                        less than 1.0, then data-aware mixed precision assignment will be applied.
  --sym                 Whether to apply symmetric quantization. This argument is related to integer-typed
                        --weight-format and --quant-mode options. In case of full or mixed quantization (--quant-mode)
                        symmetric quantization will be applied to weights in any case, so only activation quantization
                        will be affected by --sym argument. For weight-only quantization (--weight-format) --sym
                        argument does not affect backup precision. Examples: (1) --weight-format int8 --sym => int8
                        symmetric quantization of weights; (2) --weight-format int4 => int4 asymmetric quantization of
                        weights; (3) --weight-format int4 --sym --backup-precision int8_asym => int4 symmetric
                        quantization of weights with int8 asymmetric backup precision; (4) --quant-mode int8 --sym =>
                        weights and activations are quantized to int8 symmetric data type; (5) --quant-mode int8 =>
                        activations are quantized to int8 asymmetric data type, weights -- to int8 symmetric data type;
                        (6) --quant-mode int4_f8e5m2 --sym => activations are quantized to f8e5m2 data type, weights --
                        to int4 symmetric data type.
  --group-size GROUP_SIZE
                        The group size to use for quantization. Recommended value is 128 and -1 uses per-column
                        quantization.
  --backup-precision {none,int8_sym,int8_asym}
                        Defines a backup precision for mixed-precision weight compression. Only valid for 4-bit weight
                        formats. If not provided, backup precision is int8_asym. 'none' stands for original floating-
                        point precision of the model weights, in this case weights are retained in their original
                        precision without any quantization. 'int8_sym' stands for 8-bit integer symmetric quantization
                        without zero point. 'int8_asym' stands for 8-bit integer asymmetric quantization with zero
                        points per each quantization group.
  --dataset DATASET     The dataset used for data-aware compression or quantization with NNCF. For language models you
                        can use the one from the list ['auto','wikitext2','c4','c4-new']. With 'auto' the dataset will
                        be collected from model's generations. For diffusion models it should be on of
                        ['conceptual_captions','laion/220k-GPT4Vision-captions-from-LIVIS','laion/filtered-wit']. For
                        visual language models the dataset must be set to 'contextual'. Note: if none of the data-aware
                        compression algorithms are selected and ratio parameter is omitted or equals 1.0, the dataset
                        argument will not have an effect on the resulting model. Note: for text generation task,
                        datasets with English texts such as 'wikitext2','c4' or 'c4-new' usually work fine even for
                        non-English models.
  --all-layers          Whether embeddings and last MatMul layers should be compressed to INT4. If not provided an
                        weight compression is applied, they are compressed to INT8.
  --awq                 Whether to apply AWQ algorithm. AWQ improves generation quality of INT4-compressed LLMs. If
                        dataset is provided, a data-aware activation-based version of the algorithm will be executed,
                        which requires additional time. Otherwise, data-free AWQ will be applied which relies on
                        per-column magnitudes of weights instead of activations. Note: it is possible that there will
                        be no matching patterns in the model to apply AWQ, in such case it will be skipped.
  --scale-estimation    Indicates whether to apply a scale estimation algorithm that minimizes the L2 error between
                        the original and compressed layers. Providing a dataset is required to run scale estimation.
                        Please note, that applying scale estimation takes additional memory and time.
  --gptq                Indicates whether to apply GPTQ algorithm that optimizes compressed weights in a layer-wise
                        fashion to minimize the difference between activations of a compressed and original layer.
                        Please note, that applying GPTQ takes additional memory and time.
  --lora-correction     Indicates whether to apply LoRA Correction algorithm. When enabled, this algorithm introduces
                        low-rank adaptation layers in the model that can recover accuracy after weight compression at
                        some cost of inference latency. Please note, that applying LoRA Correction algorithm takes
                        additional memory and time.
  --sensitivity-metric SENSITIVITY_METRIC
                        The sensitivity metric for assigning quantization precision to layers. It can be one of the
                        following: ['weight_quantization_error', 'hessian_input_activation',
                        'mean_activation_variance', 'max_activation_variance', 'mean_activation_magnitude'].
  --quantization-statistics-path QUANTIZATION_STATISTICS_PATH
                        Directory path to dump/load data-aware weight-only quantization statistics. This is useful when
                        running data-aware quantization multiple times on the same model and dataset to avoid
                        recomputing statistics. This option is applicable exclusively for weight-only quantization.
                        Please note that the statistics depend on the dataset, so if you change the dataset, you should
                        also change the statistics path to avoid confusion.
  --num-samples NUM_SAMPLES
                        The maximum number of samples to take from the dataset for quantization.
  --disable-stateful    Disable stateful converted models, stateless models will be generated instead. Stateful models
                        are produced by default when this key is not used. In stateful models all kv-cache inputs and
                        outputs are hidden in the model and are not exposed as model inputs and outputs. If --disable-
                        stateful option is used, it may result in sub-optimal inference performance. Use it when you
                        intentionally want to use a stateless model, for example, to be compatible with existing
                        OpenVINO native inference code that expects KV-cache inputs and outputs in the model.
  --disable-convert-tokenizer
                        Do not add converted tokenizer and detokenizer OpenVINO models.
  --smooth-quant-alpha SMOOTH_QUANT_ALPHA
                        SmoothQuant alpha parameter that improves the distribution of activations before MatMul layers
                        and reduces quantization error. Valid only when activations quantization is enabled.
```

You can also apply fp16, 8-bit or 4-bit weight-only quantization on the Linear, Convolutional and Embedding layers when exporting your model by setting `--weight-format` to respectively `fp16`, `int8` or `int4`.

Export with INT8 weights compression:
```bash
optimum-cli export openvino --model meta-llama/Meta-Llama-3-8B --weight-format int8 ov_model/
```

Export with INT4 weights compression:
```bash
optimum-cli export openvino --model meta-llama/Meta-Llama-3-8B --weight-format int4 ov_model/
```

Export with INT4 weights compression and data-free AWQ algorithm:
```bash
optimum-cli export openvino --model meta-llama/Meta-Llama-3-8B --weight-format int4 --awq ov_model/
```

Export with INT4 weights compression and data-aware AWQ and Scale Estimation algorithms:
```bash
optimum-cli export openvino --model meta-llama/Meta-Llama-3-8B \
    --weight-format int4 --awq --scale-estimation --dataset wikitext2 ov_model/
```

For more information on the quantization parameters checkout the [documentation](inference#weight-only-quantization)


<Tip warning={true}>

Models larger than 1 billion parameters are exported to the OpenVINO format with 8-bit weights by default. You can disable it with `--weight-format fp32`.

</Tip>


Besides weight-only quantization, you can also apply full model quantization including activations by setting `--quant-mode` to preferred precision. This will quantize both weights and activations of Linear, Convolutional and some other layers to selected mode. Please see example below.

```bash
optimum-cli export openvino -m openai/whisper-large-v3-turbo --quant-mode int8 --dataset librispeech --num-samples 32 --smooth-quant-alpha 0.9 ./whisper-large-v3-turbo
```

#### Default quantization configs

For some models we maintain a set of default quantization configs ([link](https://github.com/huggingface/optimum-intel/blob/main/optimum/intel/openvino/configuration.py)). To apply a default 4-bit weight-only quantization one should provide `--weight-format int4` without any additional arguments. For int8 weight & activation quantization it should be `--quant-mode int8`. For example:

```bash
optimum-cli export openvino -m microsoft/Phi-4-mini-instruct --weight-format int4 ./Phi-4-mini-instruct
```

or

```bash
optimum-cli export openvino -m openai/clip-vit-base-patch16 --quant-mode int8 ./clip-vit-base-patch16
```


### Decoder models

For models with a decoder, we enable the re-use of past keys and values by default. This allows to avoid recomputing the same intermediate activations at each generation step. To export the model without, you will need to remove the `-with-past` suffix when specifying the task.

| With K-V cache                           | Without K-V cache                    |
|------------------------------------------|--------------------------------------|
| `text-generation-with-past`              | `text-generation`                    |
| `text2text-generation-with-past`         | `text2text-generation`               |
| `automatic-speech-recognition-with-past` | `automatic-speech-recognition`       |


### Diffusion models

When Stable Diffusion models are exported to the OpenVINO format, they are decomposed into different components that are later combined during inference:

* Text encoder(s)
* U-Net
* VAE encoder
* VAE decoder

To export your Stable Diffusion XL model to the OpenVINO IR format with the CLI you can do as follows:

```bash
optimum-cli export openvino --model stabilityai/stable-diffusion-xl-base-1.0 ov_sdxl/
```

You can also apply hybrid quantization during model export. For example:
```bash
optimum-cli export openvino --model stabilityai/stable-diffusion-xl-base-1.0 \
    --weight-format int8 --dataset conceptual_captions ov_sdxl/
```

For more information about hybrid quantization, take a look at this jupyter [notebook](https://github.com/huggingface/optimum-intel/blob/main/notebooks/openvino/stable_diffusion_hybrid_quantization.ipynb).

## When loading your model

You can also load your PyTorch checkpoint and convert it to the OpenVINO format on-the-fly, by setting `export=True` when loading your model.

To easily save the resulting model, you can use the `save_pretrained()` method, which will save both the BIN and XML files describing the graph. It is useful to save the tokenizer to the same directory, to enable easy loading of the tokenizer for the model.


```diff
- from transformers import AutoModelForCausalLM
+ from optimum.intel import OVModelForCausalLM
  from transformers import AutoTokenizer

  model_id = "meta-llama/Meta-Llama-3-8B"
- model = AutoModelForCausalLM.from_pretrained(model_id)
+ model = OVModelForCausalLM.from_pretrained(model_id, export=True)
  tokenizer = AutoTokenizer.from_pretrained(model_id)

  save_directory = "ov_model"
  model.save_pretrained(save_directory)
  tokenizer.save_pretrained(save_directory)
```

## After loading your model

```python
from transformers import AutoModelForCausalLM
from optimum.exporters.openvino import export_from_model

model = AutoModelForCausalLM.from_pretrained("meta-llama/Meta-Llama-3-8B")
export_from_model(model, output="ov_model", task="text-generation-with-past")
```

Once the model is exported, you can now [load your OpenVINO model](inference) by replacing the `AutoModelForXxx` class with the corresponding `OVModelForXxx` class.

## Troubleshooting

Some models do not work with the latest transformers release. You may see an error message with a maximum supported version. To export these models, install a transformers version that supports the model, for example `pip install transformers==4.53.3`. 
The supported transformers versions compatible with each optimum-intel release are listed on the [Github releases page](https://github.com/huggingface/optimum-intel/releases/).

### Optimization
https://huggingface.co/docs/optimum.intel/v1.26.0/openvino/optimization.md

# Optimization

🤗 Optimum Intel provides an `openvino` package that enables you to apply a variety of model quantization methods on many models hosted on the 🤗 hub using the [NNCF](https://docs.openvino.ai/2024/openvino-workflow/model-optimization.html) framework.


Quantization is a technique to reduce the computational and memory costs of running inference by representing the weights and / or the activations with lower precision data types like 8-bit or 4-bit.

## Weight-only Quantization

Quantization can be applied on the model's Linear, Convolutional and Embedding layers, enabling the loading of large models on memory-limited devices. For example, when applying 8-bit quantization, the resulting model will be x4 smaller than its fp32 counterpart. For 4-bit quantization, the reduction in memory could theoretically reach x8, but is closer to x6 in practice.


### 8-bit

For the 8-bit weight quantization you can provide `quantization_config` equal to `OVWeightQuantizationConfig(bits=8)` to load your model's weights in 8-bit:

```python
from optimum.intel import OVModelForCausalLM, OVWeightQuantizationConfig

model_id = "helenai/gpt2-ov"
quantization_config = OVWeightQuantizationConfig(bits=8)
model = OVModelForCausalLM.from_pretrained(model_id, quantization_config=quantization_config)

# Saves the int8 model that will be x4 smaller than its fp32 counterpart
model.save_pretrained(saving_directory)
```

Weights of language models inside vision-language pipelines can be quantized in a similar way:
```python
model = OVModelForVisualCausalLM.from_pretrained(
    "llava-hf/llava-v1.6-mistral-7b-hf",
    quantization_config=quantization_config
)
```

<Tip warning={true}>

If quantization_config is not provided, model will be exported in 8 bits by default when it has more than 1 billion parameters. You can disable it with `load_in_8bit=False`.

</Tip>


### 4-bit

4-bit weight quantization can be achieved in a similar way:

```python
from optimum.intel import OVModelForCausalLM

model = OVModelForCausalLM.from_pretrained(model_id, quantization_config={"bits": 4})
```

For some models, we provide preconfigured 4-bit weight-only quantization [configurations](https://github.com/huggingface/optimum-intel/blob/main/optimum/intel/openvino/configuration.py) that offer a good trade-off between quality and speed. This default 4-bit configuration is applied automatically when you specify `quantization_config={"bits": 4}`.

Or for vision-language pipelines:
```python
model = OVModelForVisualCausalLM.from_pretrained(
    "llava-hf/llava-v1.6-mistral-7b-hf",
    quantization_config={"bits": 4}
)
```

You can tune quantization parameters to achieve a better performance accuracy trade-off as follows:

```python
from optimum.intel import OVWeightQuantizationConfig

quantization_config = OVWeightQuantizationConfig(
    bits=4,
    sym=False,
    ratio=0.8,
    quant_method="awq",
    dataset="wikitext2"
)
```

Note: `OVWeightQuantizationConfig` also accepts keyword arguments that are not listed in its constructor. In this case such arguments will be passed directly to `nncf.compress_weights()` call. This is useful for passing additional parameters to the quantization algorithm.

By default the quantization scheme will be [asymmetric](https://github.com/openvinotoolkit/nncf/blob/develop/docs/usage/training_time_compression/other_algorithms/LegacyQuantization.md#asymmetric-quantization), to make it [symmetric](https://github.com/openvinotoolkit/nncf/blob/develop/docs/usage/training_time_compression/other_algorithms/LegacyQuantization.md#symmetric-quantization) you can add `sym=True`.

For 4-bit quantization you can also specify the following arguments in the quantization configuration :
* The `group_size` parameter will define the group size to use for quantization, `-1` it will results in per-column quantization.
* The `ratio` parameter controls the ratio between 4-bit and 8-bit quantization. If set to 0.9, it means that 90% of the layers will be quantized to `int4` while 10% will be quantized to `int8`.

Smaller `group_size` and `ratio` values usually improve accuracy at the sacrifice of the model size and inference latency.

Quality of 4-bit weight compressed model can further be improved by employing one of the following data-dependent methods:
* **AWQ** which stands for Activation Aware Quantization is an algorithm that tunes model weights for more accurate 4-bit compression. It slightly improves generation quality of compressed LLMs, but requires significant additional time and memory for tuning weights on a calibration dataset. Please note that it is possible that there will be no matching patterns in the model to apply AWQ, in such case it will be skipped. There is also a data-free version of AWQ available that relies on per-column magnitudes of weights instead of activations.
* **Scale Estimation** is a method that tunes quantization scales to minimize the `L2` error between the original and compressed layers. Providing a dataset is required to run scale estimation. Using this method also incurs additional time and memory overhead.
* **GPTQ** optimizes compressed weights in a layer-wise fashion to minimize the difference between activations of a compressed and original layer.
* **LoRA Correction** mitigates quantization noise introduced during weight compression by leveraging low-rank adaptation.

Data-aware algorithms can be applied together or separately. For that, provide corresponding arguments to the 4-bit `OVWeightQuantizationConfig` together with a dataset. For example:
```python
quantization_config = OVWeightQuantizationConfig(
    bits=4,
    sym=False,
    ratio=0.8,
    quant_method="awq",
    scale_estimation=True,
    gptq=True,
    dataset="wikitext2"
)
```

Note: GPTQ and LoRA Correction algorithms can't be applied simultaneously.

## Full quantization

When applying post-training full quantization, both the weights and the activations are quantized.
To apply quantization on the activations, an additional calibration step is needed which consists in feeding a `calibration_dataset` to the network in order to estimate the quantization activations parameters.

Here is how to apply full quantization on a fine-tuned DistilBERT given your own `calibration_dataset`:

```python
from transformers import AutoTokenizer
from optimum.intel import OVQuantizer, OVModelForSequenceClassification, OVConfig, OVQuantizationConfig

model_id = "distilbert-base-uncased-finetuned-sst-2-english"
model = OVModelForSequenceClassification.from_pretrained(model_id, export=True)
tokenizer = AutoTokenizer.from_pretrained(model_id)
# The directory where the quantized model will be saved
save_dir = "ptq_model"

quantizer = OVQuantizer.from_pretrained(model)

# Apply full quantization and export the resulting quantized model to OpenVINO IR format
ov_config = OVConfig(quantization_config=OVQuantizationConfig())
quantizer.quantize(ov_config=ov_config, calibration_dataset=calibration_dataset, save_directory=save_dir)
# Save the tokenizer
tokenizer.save_pretrained(save_dir)
```

The calibration dataset can also be created easily using your `OVQuantizer`:

```python
from functools import partial

def preprocess_function(examples, tokenizer):
    return tokenizer(examples["sentence"], padding="max_length", max_length=128, truncation=True)

# Create the calibration dataset used to perform full quantization
calibration_dataset = quantizer.get_calibration_dataset(
    "glue",
    dataset_config_name="sst2",
    preprocess_function=partial(preprocess_function, tokenizer=tokenizer),
    num_samples=300,
    dataset_split="train",
)
```


The `quantize()` method applies post-training quantization and export the resulting quantized model to the OpenVINO Intermediate Representation (IR). The resulting graph is represented with two files: an XML file describing the network topology and a binary file describing the weights. The resulting model can be run on any target Intel device.


### Speech-to-text Models Quantization

The speech-to-text Whisper model can be quantized without the need for preparing a custom calibration dataset. Please see example below.

```python
model_id = "openai/whisper-tiny"
ov_model = OVModelForSpeechSeq2Seq.from_pretrained(
    model_id,
    stateful=False,
    quantization_config=OVQuantizationConfig(
        num_samples=10,
        dataset="librispeech",
        processor=model_id,
        smooth_quant_alpha=0.95,
    )
)
```

With this, encoder, decoder and decoder-with-past models of the Whisper pipeline will be fully quantized, including activations.

##  Hybrid quantization

Traditional optimization methods like post-training 8-bit quantization do not work well for Stable Diffusion (SD) models and can lead to poor generation results. On the other hand, weight compression does not improve performance significantly when applied to Stable Diffusion models, as the size of activations is comparable to weights.
The U-Net component takes up most of the overall execution time of the pipeline. Thus, optimizing just this one component can bring substantial benefits in terms of inference speed while keeping acceptable accuracy without fine-tuning. Quantizing the rest of the diffusion pipeline does not significantly improve inference performance but could potentially lead to substantial accuracy degradation.
Therefore, the proposal is to apply quantization in *hybrid mode* for the U-Net model and weight-only quantization for the rest of the pipeline components :
* U-Net : quantization applied on both the weights and activations 
* The text encoder, VAE encoder / decoder : quantization applied on the weights 

The hybrid mode involves the quantization of weights in MatMul and Embedding layers, and activations of other layers, facilitating accuracy preservation post-optimization while reducing the model size.

The `quantization_config` is utilized to define optimization parameters for optimizing the SD pipeline. To enable hybrid quantization, specify the quantization dataset in the `quantization_config`. If the dataset is not defined, weight-only quantization will be applied on all components.

```python
from optimum.intel import OVStableDiffusionPipeline, OVWeightQuantizationConfig

model = OVStableDiffusionPipeline.from_pretrained(
    model_id,
    export=True,
    quantization_config=OVWeightQuantizationConfig(bits=8, dataset="conceptual_captions"),
)
```


For more details, please refer to the corresponding NNCF [documentation](https://github.com/openvinotoolkit/nncf/blob/develop/docs/usage/post_training_compression/weights_compression/Usage.md).


## Mixed Quantization

Mixed quantization is a technique that combines weight-only quantization with full quantization. During mixed quantization we separately quantize:
1. weights of weighted layers to one precision, and
2. activations (and possibly, weights, if some were skipped at the first step) of other supported layers to another precision.

By default, weights of all weighted layers are quantized in the first step. In the second step activations of weighted and non-weighted layers are quantized. If some layers are instructed to be ignored in the first step with `weight_quantization_config.ignored_scope` parameter, both weights and activations of these layers are quantized to the precision given in the `full_quantization_config`.

When running this kind of optimization through Python API, `OVMixedQuantizationConfig` should be used. In such case the precision for the first step should be provided with `weight_quantization_config` argument and the precision for the second step with `full_quantization_config` argument. For example:

```python
model = OVModelForCausalLM.from_pretrained(
    'TinyLlama/TinyLlama-1.1B-Chat-v1.0',
    quantization_config=OVMixedQuantizationConfig(
        weight_quantization_config=OVWeightQuantizationConfig(bits=4, dtype='nf4'),
        full_quantization_config=OVQuantizationConfig(dtype='f8e4m3', dataset='wikitext2')
    )
)
```

To apply mixed quantization through CLI, the `--quant-mode` argument should be used. For example:

```bash
optimum-cli export openvino -m TinyLlama/TinyLlama-1.1B-Chat-v1.0 --quant-mode nf4_f8e4m3 --dataset wikitext2 ./save_dir
```

Don't forget to provide a dataset since it is required for the calibration procedure during full quantization.


## Pipeline Quantization

There are multimodal pipelines that consist of multiple components, such as Stable Diffusion or Visual Language models. In these cases, there may be a need to apply different quantization methods to different components of the pipeline. For example, you may want to apply int4 data-aware weight-only quantization to a language model in visual-language pipeline, while applying int8 weight-only quantization to other components. In this case you can use the `OVPipelineQuantizationConfig` class to specify the quantization configuration for each component of the pipeline.

For example, the code below quantizes weights and activations of a language model inside InternVL2-1B, compresses weights of a text embedding model and skips any quantization for vision embedding model.

```python
from optimum.intel import OVModelForVisualCausalLM
from optimum.intel import OVPipelineQuantizationConfig, OVQuantizationConfig, OVWeightQuantizationConfig

model_id = "OpenGVLab/InternVL2-1B"
model = OVModelForVisualCausalLM.from_pretrained(
    model_id,
    export=True,
    trust_remote_code=True,
    quantization_config=OVPipelineQuantizationConfig(
        quantization_configs={
            "lm_model": OVQuantizationConfig(bits=8),
            "text_embeddings_model": OVWeightQuantizationConfig(bits=8),
        },
        dataset="contextual",
        trust_remote_code=True,
    )
)
```

### Generate images with Diffusion models
https://huggingface.co/docs/optimum.intel/v1.26.0/openvino/tutorials/diffusers.md

# Generate images with Diffusion models

## Stable Diffusion

Stable Diffusion models can also be used when running inference with OpenVINO. When Stable Diffusion models
are exported to the OpenVINO format, they are decomposed into different components that are later combined during inference:
- The text encoder
- The U-NET
- The VAE encoder
- The VAE decoder

| Task                                 | Auto Class                           |
|--------------------------------------|--------------------------------------|
| `text-to-image`                      | `OVStableDiffusionPipeline`          |
| `image-to-image`                     | `OVStableDiffusionImg2ImgPipeline`   |
| `inpaint`                            | `OVStableDiffusionInpaintPipeline`   |


### Text-to-Image
Here is an example of how you can load an OpenVINO Stable Diffusion model and run inference using OpenVINO Runtime:

```python
from optimum.intel import OVStableDiffusionPipeline

model_id = "echarlaix/stable-diffusion-v1-5-openvino"
pipeline = OVStableDiffusionPipeline.from_pretrained(model_id)
prompt = "sailing ship in storm by Rembrandt"
images = pipeline(prompt).images
```

To load your PyTorch model and convert it to OpenVINO on the fly, you can set `export=True`.

```python
model_id = "runwayml/stable-diffusion-v1-5"
pipeline = OVStableDiffusionPipeline.from_pretrained(model_id, export=True)
# Don't forget to save the exported model
pipeline.save_pretrained("openvino-sd-v1-5")
```

To further speed up inference, the model can be statically reshaped :

```python
# Define the shapes related to the inputs and desired outputs
batch_size, num_images, height, width = 1, 1, 512, 512
# Statically reshape the model
pipeline.reshape(batch_size=batch_size, height=height, width=width, num_images_per_prompt=num_images)
# Compile the model before the first inference
pipeline.compile()

# Run inference
images = pipeline(prompt, height=height, width=width, num_images_per_prompt=num_images).images
```

In case you want to change any parameters such as the outputs height or width, you'll need to statically reshape your model once again.

</div>

### Text-to-Image with Textual Inversion
Here is an example of how you can load an OpenVINO Stable Diffusion model with pre-trained textual inversion embeddings and run inference using OpenVINO Runtime:


First, you can run original pipeline without textual inversion
```python
from optimum.intel import OVStableDiffusionPipeline
import numpy as np

model_id = "echarlaix/stable-diffusion-v1-5-openvino"
prompt = "A <cat-toy> back-pack"
# Set a random seed for better comparison
np.random.seed(42)

pipeline = OVStableDiffusionPipeline.from_pretrained(model_id, export=False, compile=False)
pipeline.compile()
image1 = pipeline(prompt, num_inference_steps=50).images[0]
image1.save("stable_diffusion_v1_5_without_textual_inversion.png")
```

Then, you can load [sd-concepts-library/cat-toy](https://huggingface.co/sd-concepts-library/cat-toy) textual inversion embedding and run pipeline with same prompt again
```python
# Reset stable diffusion pipeline
pipeline.clear_requests()

# Load textual inversion into stable diffusion pipeline
pipeline.load_textual_inversion("sd-concepts-library/cat-toy", "<cat-toy>")

# Compile the model before the first inference
pipeline.compile()
image2 = pipeline(prompt, num_inference_steps=50).images[0]
image2.save("stable_diffusion_v1_5_with_textual_inversion.png")
```
The left image shows the generation result of original stable diffusion v1.5, the right image shows the generation result of stable diffusion v1.5 with textual inversion.

```python
from optimum.intel import OVStableDiffusionXLPipeline

model_id = "stabilityai/stable-diffusion-xl-base-1.0"

### Text-to-Image with Textual Inversion

Here is an example of how you can load an SDXL OpenVINO model from [stabilityai/stable-diffusion-xl-base-1.0](https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0) with pre-trained textual inversion embeddings and run inference using OpenVINO Runtime:


First, you can run original pipeline without textual inversion
```python
from optimum.intel import OVStableDiffusionXLPipeline
import numpy as np

model_id = "stabilityai/stable-diffusion-xl-base-1.0"
prompt = "charturnerv2, multiple views of the same character in the same outfit, a character turnaround wearing a red jacket and black shirt, best quality, intricate details."
# Set a random seed for better comparison
np.random.seed(112)

base = OVStableDiffusionXLPipeline.from_pretrained(model_id, export=False, compile=False)
base.compile()
image1 = base(prompt, num_inference_steps=50).images[0]
image1.save("sdxl_without_textual_inversion.png")
```

Then, you can load [charturnerv2](https://civitai.com/models/3036/charturner-character-turnaround-helper-for-15-and-21) textual inversion embedding and run pipeline with same prompt again
```python
# Reset stable diffusion pipeline
base.clear_requests()

# Load textual inversion into stable diffusion pipeline
base.load_textual_inversion("./charturnerv2.pt", "charturnerv2")

# Compile the model before the first inference
base.compile()
image2 = base(prompt, num_inference_steps=50).images[0]
image2.save("sdxl_with_textual_inversion.png")
```

### Image-to-Image

Here is an example of how you can load a PyTorch SDXL model, convert it to OpenVINO on-the-fly and run inference using OpenVINO Runtime for *image-to-image*:

```python
from optimum.intel import OVStableDiffusionXLImg2ImgPipeline
from diffusers.utils import load_image

model_id = "stabilityai/stable-diffusion-xl-refiner-1.0"
pipeline = OVStableDiffusionXLImg2ImgPipeline.from_pretrained(model_id, export=True)

url = "https://huggingface.co/datasets/optimum/documentation-images/resolve/main/intel/openvino/sd_xl/castle_friedrich.png"
image = load_image(url).convert("RGB")
prompt = "medieval castle by Caspar David Friedrich"
image = pipeline(prompt, image=image).images[0]
# Don't forget to save your OpenVINO model so that you can load it without exporting it with `export=True`
pipeline.save_pretrained("openvino-sd-xl-refiner-1.0")
```


### Refining the image output

The image can be refined by making use of a model like [stabilityai/stable-diffusion-xl-refiner-1.0](https://huggingface.co/stabilityai/stable-diffusion-xl-refiner-1.0). In this case, you only have to output the latents from the base model.


```python
from optimum.intel import OVStableDiffusionXLImg2ImgPipeline

model_id = "stabilityai/stable-diffusion-xl-refiner-1.0"
refiner = OVStableDiffusionXLImg2ImgPipeline.from_pretrained(model_id, export=True)

image = base(prompt=prompt, output_type="latent").images[0]
image = refiner(prompt=prompt, image=image[None, :]).images[0]
```

| `text-to-image`                      | `OVLatentConsistencyModelPipeline`   |


### Text-to-Image

Here is an example of how you can load a Latent Consistency Model (LCM) from [SimianLuo/LCM_Dreamshaper_v7](https://huggingface.co/SimianLuo/LCM_Dreamshaper_v7) and run inference using OpenVINO :

```python
from optimum.intel import OVLatentConsistencyModelPipeline

model_id = "SimianLuo/LCM_Dreamshaper_v7"
pipeline = OVLatentConsistencyModelPipeline.from_pretrained(model_id, export=True)
prompt = "sailing ship in storm by Leonardo da Vinci"
images = pipeline(prompt, num_inference_steps=4, guidance_scale=8.0).images
```

### Inference
https://huggingface.co/docs/optimum.intel/v1.26.0/ipex/inference.md

# Inference

Optimum Intel can be used to load models from the [Hub](https://huggingface.co/models) and create pipelines to run inference with IPEX optimizations (including patching with custom operators, weight prepacking and graph mode) on a variety of Intel processors. For now support is only enabled for CPUs.


## Loading

You can load your model and apply IPEX optimizations (apply torch.compile except text-generation tasks). For supported architectures like LLaMA, BERT and ViT, further optimizations will be applied by patching the model to use custom operators.
For now, support is enabled for Intel CPU/GPU. Previous models converted to TorchScript will be deprecated in v1.22.

```diff
  import torch
  from transformers import AutoTokenizer, pipeline
- from transformers import AutoModelForCausalLM
+ from optimum.intel import IPEXModelForCausalLM

  model_id = "gpt2"
- model = AutoModelForCausalLM.from_pretrained(model_id, torch_dtype=torch.bfloat16)
+ model = IPEXModelForCausalLM.from_pretrained(model_id, torch_dtype=torch.bfloat16)
  tokenizer = AutoTokenizer.from_pretrained(model_id)
  pipe = pipeline("text-generation", model=model, tokenizer=tokenizer)
  results = pipe("He's a dreadful magician and")
