MoTCoder: Elevating Large Language Models with Modular of Thought for Challenging Programming Tasks

• 🤗 Data • 🤗 Model • 🐱 Code • 📃 Paper

Large Language Models (LLMs) have showcased impressive capabilities in handling straightforward programming tasks. However, their performance tends to falter when confronted with more challenging programming problems. We observe that conventional models often generate solutions as monolithic code blocks, restricting their effectiveness in tackling intricate questions. To overcome this limitation, we present Modular-of-Thought Coder (MoTCoder). We introduce a pioneering framework for MoT instruction tuning, designed to promote the decomposition of tasks into logical sub-tasks and sub-modules. Our investigations reveal that, through the cultivation and utilization of sub-modules, MoTCoder significantly improves both the modularity and correctness of the generated solutions, leading to substantial relative pass@1 improvements of 12.9% on APPS and 9.43% on CodeContests.

Environment

Install the dependencies.

python -m pip install -e .

Evaluation Datasets

APPS Dataset

The APPs dataset [github] can be download from huggingface.

CodeContests Dataset

The CodeContests dataset [github] can be download from huggingface. For CodeContests, convert your dataset to the same format as APPs for utilizting APPs evaluation metrics:

python src/convert_codecontest_dataset.py $SRC_DIR $DST_DIR

Inference

You can download our MoTCoder for evaluation from huggingface. We provide the inference command to reproduce the results in our paper.

• If you want to use modular-of-thought inference prompt, set prompt_type=FORMAT_PROMPT.
• If you want to use normal inference prompt, set prompt_type=NORMAL_FORMAT_PROMPT.

First generate the solutions for you targeted evaluation dataset. Choice 1: VLLM (Recommended) To install the requreiments:

pip install vllm

Inference:

python src/inference_vllm.py \
    --model_path $model_path \
    --data_path $data_path \
    --solution_path $solution_path \
    --prompt_type $prompt_type

Choice 2: transformers Inference:

python src/inference.py \
    $model_path \
    $data_path \
    $solution_path \
    $prompt_type

APPs Evaluation

For APPs evaluation, choices of $level$ include $introductory, interview, competition$.

python src/test_leetcode.py \
    --solutions_path $solution_path \
    --data_path $data_path \
    --save_path $result_path \
    --level $level
