DROP Explorer

Use DROP Explorer to better understand DROP, Quoref and the models' predictions.

Usage

The commands listed in this section need to be run from the root directory of the repository.

First, install prerequisites with
pip install -r requirements.txt

Commands

• Train a model:

allennlp train configs/[config file] -s [training_directory] --include-package src

• Output predictions by a model:

allennlp predict model.tar.gz drop_data/drop_dataset_dev.json --predictor machine-comprehension \
--cuda-device 0 --output-file predictions.jsonl --use-dataset-reader --include-package src \
-o "{'validation_dataset_reader.pickle.action': 'None'}"

• Evaluate a model (unofficial evaluation code, faster):

allennlp evaluate model.tar.gz drop_data/drop_dataset_dev.json --cuda-device 0 --output-file eval.json \
--include-package src -o "{'validation_dataset_reader.pickle.action': 'None'}"

• Evaluate a model (official evaluation code, slower):

  python tools/generate_submission_predictions.py --archive_file model.tar.gz \
  --input_file drop_data/drop_dataset_dev.json --cuda-device 0 --output_file predictions.json \
  --include-package src
  

  python -m allennlp.tools.drop_eval --gold_path drop_data/drop_dataset_dev.json \
  --prediction_path predictions.json --output_path metrics.json
  

Trained Models

• RoBERTa TASE_IO + SSE - Trained on DROP (config)
• RoBERTa TASE_IO - Trained on DROP (config)
