Optimum Habana is the interface between the Transformers library and Habana's Gaudi processor (HPU). It provides a set of tools enabling easy and fast model loading and fine-tuning 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 Transformers models at hf.co/hardware/habana.

Bert Base model HPU configuration

This model only contains the GaudiConfig file for running the bert-base-uncased model on Habana's Gaudi processors (HPU).

This model contains no model weights, only a GaudiConfig.

This enables to specify:

• use_habana_mixed_precision: whether to use Habana Mixed Precision (HMP)
  • hmp_opt_level: optimization level for HMP, see here for a detailed explanation
  • hmp_bf16_ops: list of operators that should run in bf16
  • hmp_fp32_ops: list of operators that should run in fp32
  • hmp_is_verbose: verbosity
• 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

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.

Here is a question-answering example script to fine-tune a model on SQuAD. You can run it with BERT with the following command:

python run_qa.py \
  --model_name_or_path bert-base-uncased \
  --gaudi_config_name Habana/bert-base-uncased \
  --dataset_name squad \
  --do_train \
  --do_eval \
  --per_device_train_batch_size 24 \
  --per_device_eval_batch_size 8 \
  --learning_rate 3e-5 \
  --num_train_epochs 2 \
  --max_seq_length 384 \
  --output_dir /tmp/squad/ \
  --use_habana \
  --use_lazy_mode \
  --throughput_warmup_steps 2
