Distilling Step-by-Step!

Code for paper Distilling Step-by-Step! Outperforming Larger Language Models with Less Training Data and Smaller Model Sizes

Environment Setup

• Setup Conda environment:

conda create --name distill python=3.10.6 -y
conda activate distill
conda install -y pytorch==1.12.1 torchvision==0.13.1 torchaudio==0.12.1 cudatoolkit=11.3 -c pytorch
pip install git+https://github.com/huggingface/transformers@v4.24.0 datasets sentencepiece protobuf==3.20.* tensorboardX

• Extract datasets to datasets/:

unzip datasets.zip

Command Usages

Args usages

• --from_pretrained: google/t5-v1_1-small, google/t5-v1_1-base, google/t5-v1_1-large, google/t5-v1_1-xxl
• --dataset: esnli, anli1, cqa, svamp
• --label_type:
  • --label_type gt: Use GT label for training
  • --label_type llm: Use LLM predicted label for training
• --alpha: Task weight for multi-task training. Loss = alpha * label_prediction_loss + (1 - alpha) * rationale_generation_loss
  • --alpha 0.5: recommended
• --batch_size: Batch size
• --grad_steps: Gradient accumulation step
• --max_input_length: Maximum input length
• --eval_steps: How many steps to evaluate the model during training
• --max_steps: Maximum steps for training
• --run: Random seed to use
• --model_type:
  • standard: Standard finetuning (--label_type gt) or distillation (--label_type llm)
  • task_prefix: Distilling step-by-step
• --parallelize: Model parallelism

Example usages

• Standard finetuning:

python run.py --from_pretrained google/t5-v1_1-base --dataset cqa --model_type standard --label_type gt --batch_size 64

• Distilling step-by-step with GT label and PaLM rationale:

python run.py --from_pretrained google/t5-v1_1-base --dataset cqa --model_type task_prefix --label_type gt --llm palm --alpha 0.5 --batch_size 64

• Standard distillation:

python run.py --from_pretrained google/t5-v1_1-base --dataset cqa --model_type standard --label_type llm --batch_size 64

• Distilling step-by-step with PaLM label and PaLM rationale:

python run.py --from_pretrained google/t5-v1_1-base --dataset cqa --model_type task_prefix --label_type llm --llm palm --alpha 0.5 --batch_size 64
