}

This code is reimplemented as a fork of huggingface/transformers.

Setup and Dependencies

This code is implemented using PyTorch v1.8.0, and provides out of the box support with CUDA 11.2 Anaconda is the recommended to set up this codebase.

# https://pytorch.org
conda install pytorch==1.8.0 torchvision==0.9.0 torchaudio==0.8.0 cudatoolkit=11.1 -c pytorch -c conda-forge
pip install -r requirements.txt

Preparing Data and Checkpoints

Post-trained and fine-tuned Checkpoints

We provide following post-trained and fine-tuned checkpoints.

Data pkl for Fine-tuning (Response Selection)

We used the following data for post-training and fine-tuning

fine-grained post-training dataset and fine-tuning dataset for 3 benchmarks (ubuntu, douban, e-commerce)

Original version for each dataset is availble in Ubuntu Corpus V1, Douban Corpus, and E-Commerce Corpus, respectively.

Data_processing.py

Post-training Examples

(Ubuntu Corpus V1, Douban Corpus, E-commerce Corpus)

python -u FPT/ubuntu_final.py --num_train_epochs 25
python -u FPT/douban_final.py --num_train_epochs 27
python -u FPT/e_commmerce_final.py --num_train_epochs 34

Fine-tuning Examples

(Ubuntu Corpus V1, Douban Corpus, E-commerce Corpus)

Taining

To train the model, set `--is_training`
python -u Fine-Tuning/Response_selection.py --task ubuntu --is_training
python -u Fine-Tuning/Response_selection.py --task douban --is_training
python -u Fine-Tuning/Response_selection.py --task e_commerce --is_training

Testing

python -u Fine-Tuning/Response_selection.py --task ubuntu
python -u Fine-Tuning/Response_selection.py --task douban 
python -u Fine-Tuning/Response_selection.py --task e_commerce
