Todo

  • model was trained on the joint version of bAbI (all 20 tasks simultaneously), using the full dataset of 10K examples per task. (paper experiments)

Config

Can control all Experimental environment.

  print_verbose: False
  debug: False

slack:
  webhook_url: ""                  # after training notify you using slack-webhook
  • debug mode : using tfdbg

Usage

Install requirements.

pip install -r requirements.txt

Then, prepare dataset.

sh scripts/fetch_babi_data.sh

Finally, start train and evaluate model

python main.py --config bAbi_task1 --mode train_and_evaluate

Experiments modes

✅ : Working
◽ : Not tested yet.

  • evaluate : Evaluate on the evaluation data.
  • extend_train_hooks : Extends the hooks for training.
  • reset_export_strategies : Resets the export strategies with the new_export_strategies.
  • run_std_server : Starts a TensorFlow server and joins the serving thread.
  • test : Tests training, evaluating and exporting the estimator for a single step.
  • train : Fit the estimator using the training data.
  • train_and_evaluate : Interleaves training and evaluation.
