It
works by offloading each component of a pipeline to the CPU for storage, and onloading to the accelerator device
when needed for computation. This method is more memory-efficient than keeping all components on the accelerator,
but the memory requirements are still quite high. For this method to work, one needs memory equivalent to size of
the model in runtime dtype + size of largest intermediate activation tensors to be able to complete the forward
pass.</li> <li>Leaf-level: In Diffusers, this can be enabled using the <code>ModelMixin::enable_sequential_cpu_offload()</code> method. It
works by offloading the lowest leaf-level parameters of the computation graph to the CPU for storage, and
onloading only the leafs to the accelerator device for computation. This uses the lowest amount of accelerator
memory, but can be slower due to the excessive number of device synchronizations.</li>`,_t,Te,Zt=`Group offloading is a middle ground between the two methods. It works by offloading groups of internal layers,
(either <code>torch.nn.ModuleList</code> or <code>torch.nn.Sequential</code>). This method uses lower memory than module-level
offloading. It is also faster than leaf-level/sequential offloading, as the number of device synchronizations is
reduced.`,yt,Ie,Pt=`Another supported feature (for CUDA devices with support for asynchronous data transfer streams) is the ability to
overlap data transfer and computation to reduce the overall execution time compared to sequential offloading. This
is enabled using layer prefetching with streams, i.e., the layer that is to be executed next starts onloading to
the accelerator device while the current layer is being executed - this increases the memory requirements slightly.
Note that this implementation also supports leaf-level offloading but can be made much faster when using streams.`,bt,B,Qe,re,Ye,Je,Oe;return v=new Wt({props:{containerStyle:"float: right; margin-left: 10px; display: inline-flex; position: relative; z-index: 10;"}}),w=new J({props:{title:"Utilities",local:"utilities",headingTag:"h1"}}),R=new J({props:{title:"numpy_to_pil",local:"diffusers.utils.numpy_to_pil",headingTag:"h2"}}),F=new j({props:{name:"diffusers.utils.numpy_to_pil",anchor:"diffusers.utils.numpy_to_pil",parameters:[{name:"images",val:""}],source:"https://github.com/huggingface/diffusers/blob/main/src/diffusers/utils/pil_utils.py#L37"}}),G=new J({props:{title:"pt_to_pil",local:"diffusers.utils.pt_to_pil",headingTag:"h2"}}),H=new j({props:{name:"diffusers.utils.pt_to_pil",anchor:"diffusers.utils.pt_to_pil",parameters:[{name:"images",val:""}],source:"https://github.com/huggingface/diffusers/blob/main/src/diffusers/utils/pil_utils.py#L27"}}),W=new J({props:{title:"load_image",local:"diffusers.utils.load_image",headingTag:"h2"}}),z=new j({props:{name:"diffusers.utils.load_image",anchor:"diffusers.utils.load_image",parameters:[{name:"image",val:": typing.Union[str, PIL.Image.Image]"},{name:"convert_method",val:": typing.Optional[typing.Callable[[PIL.Image.Image], PIL.Image.Image]] = None"}],parametersDescription:[{anchor:"diffusers.utils.load_image.image",description:`<strong>image</strong> (<code>str</code> or <code>PIL.Image.Image</code>) &#x2014;
