Not All Votes Count! Programs as Verifiers Improve Self-Consistency of Language Models for Math Reasoning

Setup

1. Create and activate a new Conda environment:

   conda create -n prove python=3.10 -y
   conda activate prove
   

2. Install the required dependencies:

   pip install -r requirements.txt
   

3. Create a .env file and add your Hugging Face token:

   HF_TOKEN=<hf_token>
   

Running Prove

Example Command

To run Prove using a single GPU, use the following command:

python eval.py \
    --num_cot 16 \
    --cot_prompt <prompt> \
    --cot_model <model> \
    --cot_temperature 0.7 \
    --cot_max_tokens 1024 \
    --cot_gpu 0 \
    --extract_prompt extract \
    --extract_model phi3_38b \
    --extract_temperature 0.0 \
    --extract_max_tokens 32 \
    --extract_gpu 0 \
    --output_to_program output2pot \
