Llemma evaluation harness

Fork of the Eleuther LM Evaluation Harness used in Azerbayev et al 2023.

Running the evaluation

See eval_scripts/generic_run.sh for an entrypoint to running evaluation on a model from the HuggingFace Hub.

The script shows the set of non-theorem-proving tasks:

SYMBOLIC=minerva_math*,gsm8k,ocw_courses
MUL_CHOICE=minerva-hendrycksTest*,math_sat_cot
TOOLS=sympy_math*,python_gsm8k

Refer to lm_eval/tasks directory for their associated implementations.

Theorem proving task

The informal-to-formal theorem proving task is kept in the minif2f-isabelle branch. Please see the README in this branch for further instructions.

Additions

This Llemma evaluation harness implemented several extensions of the Eleuther LM Evaluation Harness at the time of development. Note that these may have been implemented in the Harness subsequently. An incomplete list includes:

Tasks Supported

Below, we detail all evaluations implemented and reported in our paper.

We additionally implement the following tasks in this fork, though we do not report them in our paper due to time+space limitations:

Quick Replication Instructions

Maj@1

To run the model on desired tasks with 1 attempt, run the following sample command with your model.

MODEL=EleutherAI/llemma_7b # your HF Hub model path here
TASK=minerva_math* # select tasks as desired. This codebase supports wildcard task names.
OUT=</path/to/save/outputs>

python main.py --no_cache --model vllm --model_args pretrained=${MODEL} --tasks $TASK --output_path ${OUT} --tp_degree ${TP_DEGREE}

Maj@K

To replicate Maj@K task results, additionally pass --description_dict_path configs/majk.json to run majority voting with K attempts.

MODEL=EleutherAI/llemma_7b # your HF Hub model path here
TASK=minerva_math* # select tasks as desired. This codebase supports wildcard task names.
OUT=</path/to/save/outputs>

python main.py --no_cache --model vllm --model_args pretrained=${MODEL} --tasks $TASK --output_path ${OUT} --tp_degree ${TP_DEGREE} --description_dict_path ${HARNESS_DIR}/configs/majk.json

TP_DEGREE can be set as needed to determine how many GPUs will be used by vLLM.

Be sure to set $OUT to the desired save location for scores and model output text.

Answer Checking + Scoring

Due to heavy CPU burden, we do not calculate metrics for tasks like minerva_math that rely on checking correctness via SymPy equivalence, or tasks like sympy_math or python_gsm that require execution of model-generated Python code.

After running the model on one of these tasks, we provide utilities to perform answer checking.

Note that SymPy answer checking can be quite heavy on CPU resources and time-consuming for Maj@K at high K.

:rotating_light: WARNING: unsafe_score_sympy_math.py and unsafe_score_python_gsm.py will execute model-written Python code! Please use in a sandbox and at your own risk.

:rotating_light: WARNING: scoring scripts modify eval-harness output JSONs in-place. Back up your results files and use with caution!

To score sympy_math outputs, run:

python unsafe_score_sympy_math.py --output <path-to-results-with-sympy_math>

To score python_gsm8k outputs, run

python unsafe_score_python_gsm.py --output <path-to-results-with-python_gsm8k>

These scripts will take in a results file, read in the LM's generated programs, and execute them to check for correctness. It will then incorporate the per-sample and full-task accuracies into the results file and rewrite the entire file with these values added.

All scripts allow for a --limit X flag to be passed to only score the first X documents.

Due to the high resource cost of scoring MATH with SymPy, unsafe_score_minerva_math.py has additional requirements.

To run Sympy scoring using multiprocessing, run

python unsafe_score_minerva_math.py --output <path-to-math-result.json>

To run in a single process, run

python unsafe_score_minerva_math.py --output <path-to-math-result.json> --no_multiprocessing

Additionally, MATH scoring with SymPy is resumable--results and pass rates / accuracies for each document are saved to the results file in-place. by default, the script will not rescore already-scored documents.

Aggregation

Finally, we provide utilities for aggregating MMLU and MATH scores across subtasks, aggregating at the sample level rather than the subset level.

To aggregate MMLU-STEM scores, run:

python score_mmlu.py <path-to-mmlu-results.json>

To aggregate MATH scores, run:

python score_math.py <path-to-math-subtask-1.json>,<path-to-math-subtask-2-and-3.json>,...
