DialogWAE

It is a PyTorch implementation of the DialogWAE model described in DialogWAE: Multimodal Response Generation with Conditional Wasserstein Auto-Encoder.

Dependency

PyTorch 0.4.0
Python 3.6
NLTK

pip install -r requirements.txt

Train

Use pre-trained Word2vec Download Glove word embeddings glove.twitter.27B.200d.txt from https://nlp.stanford.edu/projects/glove/ and save it to the ./data folder. The default setting use 200 dimension word embedding trained on Twitter.
Modify the arguments at the top of train.py
Train model by
```
  python train.py --visual
```

The logs and temporary results will be printed to stdout and saved in the ./output path.

Visualize the training status in Tensorboard
```
  tensorboard --logdir output
```

Evaluation

Modify the arguments at the bottom of sample.py

Run model testing by:

    python sample.py

The outputs will be printed to stdout and generated responses will be saved at results.txt in the ./output path.
