* 7529 do not disable autocast for cuda devices * Remove typecasting error check for non-mps platforms, as a correct autocast implementation makes it a non-issue * add autocast fix to other training examples * disable native_amp for dreambooth (sdxl) * disable native_amp for pix2pix (sdxl) * remove tests from remaining files * disable native_amp on huggingface accelerator for every training example that uses it * convert more usages of autocast to nullcontext, make style fixes * make style fixes * style. * Empty-Commit --------- Co-authored-by: bghira <bghira@users.github.com> Co-authored-by: Sayak Paul <spsayakpaul@gmail.com>
Diffusers examples with Intel optimizations
This research project is not actively maintained by the diffusers team. For any questions or comments, please make sure to tag @hshen14 .
This aims to provide diffusers examples with Intel optimizations such as Bfloat16 for training/fine-tuning acceleration and 8-bit integer (INT8) for inference acceleration on Intel platforms.
Accelerating the fine-tuning for textual inversion
We accelereate the fine-tuning for textual inversion with Intel Extension for PyTorch. The examples enable both single node and multi-node distributed training with Bfloat16 support on Intel Xeon Scalable Processor.
Accelerating the inference for Stable Diffusion using Bfloat16
We start the inference acceleration with Bfloat16 using Intel Extension for PyTorch. The script is generally designed to support standard Stable Diffusion models with Bfloat16 support.
