Here are the instructions to use the code base.
This code is written in Python 3.
Run the command line below to install the package (add -e
option if you need an editable installation):
pip install .
It will automatically install the following important dependencies:
To replicate our experiments, download our datasets from Google drive. You will only need the data in the
data/modified
folder if you do not want to process the data by yourself.
You could download the weight checkpoints in the same Google drive link for inference. Use the following command to do inference without explicit planning:
python event/run/compute_all_metrics_choice.py \
--gate 2 \
--is_plan False \
--choice_num 3 \
--dataset_prefix task1-ultimate \
--load_path_sel weight/selector \
--load_path_ln weight/selector-ln \
--load_path_der weight/deriver \
> noplan_3.out
The output file will contain proof scores of all positive samples in binary classification/multiple choice. (The third choice is always the correct one.)
Use the following command to do inference with explicit planning:
python event/run/compute_all_metrics_choice.py \
--gate 2 \
--is_plan True \
--plan_early_end True \
--plan_early_end_gate 2 \
--choice_num 0 \
--dataset_prefix task1-ultimate \
--load_path_sel weight/selector \
--load_path_ln weight/selector-ln \
--load_path_der weight/deriver \
> plan_0.out
The output file will contain proof scores of all negative samples in binary classification.
Use the following command to do inference with a refined verification model:
python event/run/compute_all_metrics_choice_trained.py \
--gate 2 \
--is_plan True \
--plan_early_end True \
--plan_early_end_gate 2 \
--choice_num 0 \
--dataset_prefix task1-ultimate \
--load_path_sel weight/selector \
--load_path_ln weight/selector-ln \
--load_path_der weight/deriver \
--load_path_deberta weight/deberta \
> trained_0.out
To train the model by yourself, run
python event/run/run_supervised_selector.py
python event/run/run_supervised_deriver.py
python event/run/train_deberta_with_contrast_follow_gt_2.py
We'll improve the output format of our programs for simpler evaluation and update the readme file soon.
