Optimum Habana is the interface between the Hugging Face Transformers and Diffusers libraries and Habana's Gaudi processor (HPU). It provides a set of tools enabling easy and fast model loading, training and inference on single- and multi-HPU settings for different downstream tasks. Learn more about how to take advantage of the power of Habana HPUs to train and deploy Transformers and Diffusers models at hf.co/hardware/habana.

ViT model HPU configuration

This model only contains the GaudiConfig file for running the ViT model on Habana's Gaudi processors (HPU).

This model contains no model weights, only a GaudiConfig.

This enables to specify:

• use_fused_adam: whether to use Habana's custom AdamW implementation
• use_fused_clip_norm: whether to use Habana's fused gradient norm clipping operator
• use_torch_autocast: whether to use Torch Autocast for managing mixed precision

Usage

The model is instantiated the same way as in the Transformers library. The only difference is that there are a few new training arguments specific to HPUs.
It is strongly recommended to train this model doing bf16 mixed-precision training for optimal performance and accuracy.

Here is an image classification example script to fine-tune a model. You can run it with ViT with the following command:

python run_image_classification.py \
    --model_name_or_path google/vit-base-patch16-224-in21k \
    --dataset_name cifar10 \
    --output_dir /tmp/outputs/ \
    --remove_unused_columns False \

    --do_eval \
