RAP: Reasoning via Planning

News! We released LLM Reasoners, a library for complex reasoning with LLMs, and include the code to reproduce some experiments in RAP. Give it a try!

Source code for the paper Reasoning with Language Model is Planning with World Model

Preparation

• Warning: This code only supports LLaMA-1. Check our new library LLM Reasoners for more flexible choices of LLMs.

• Our experiments are conducted with LLaMA-33B, which takes at least 4 GPUs of 24GB memory each. The code also supports smaller LLaMA models, but other LLMs (e.g. those from Hugging Face) are not tested.

• Acquire the checkpoints of LLaMA from MetaAI following the LLaMA official repo and set up the environment variable: export LLAMA_CKPTS="YOUR_PATH_TO_LLAMA_CHECKPOINTS"

• Install all required packages for LLaMA official repo.

• (For Blocksworld) Install all required packages for GPT-Plan-Benchmark.

Blocksworld

• Set up VAL following this guide and make sure you set the environment variable export VAL="YOUR_PATH_TO_VAL"
• Run the command: CUDA_VISIBLE_DEVICES=0,1,2,3 python -m torch.distributed.run --master_port 1034 --nproc_per_node 4 run_blocksworld.py --task mcts --model_name LLaMA --ckpt_path $LLAMA_CKPTS/30B --verbose True --data data/blocksworld/step_4.json --max_depth 4 --name run_4_May26_max_depth_4_alpha_05_rollouts_10 --rollouts 10

GSM8k

• Run with: CUDA_VISIBLE_DEVICES=0,1,2,3 torchrun --nproc_per_node 4 --master-port 1054 run_gsm8k.py --llama-ckpt $LLAMA_CKPTS/30B --speedup-confidence-batch-size 2
• Use python run_gsm8k.py -- --help for details about arguments
• For RAP-Aggregation, after running RAP on GSM8k, run python aggregate_gsm8k.py --log-dir <log_dir>

ProntoQA

• Run with: CUDA_VISIBLE_DEVICES=0,1,2,3 torchrun --nproc_per_node 4 --master-port 1074 run_prontoqa.py --llama-ckpt $LLAMA_CKPTS/30B
• Use python run_prontoqa.py -- --help for details about arguments
