Stream of Search

Repository for the paper Stream of Search: Learning to Search in Language(https://arxiv.org/abs/2404.03683)

See APA code here: https://github.com/kanishkg/RLHF-APA

Installation

1. Install conda

wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh
bash Miniconda3-latest-Linux-x86_64.sh

2. Create a conda environment

conda create -n sos python=3.11
conda activate sos

3. Install the required packages

pip install -r requirements.txt

Running the code

Please update the scripts in the scripts/ directory to reflect the correct paths to the data and model checkpoints. The following steps outline the process of running the code:

1. Generate the countdown dataset

sh scripts/gen_task.sh

2. Train the model

sh scripts/train.sh

3. Generating data for STaR

sh scripts/gen_star.sh

4. Train the model with STaR

sh scripts/star.sh

5. Evaluate the model

sh scripts/eval.sh
