The code is tested under a Linux desktop with TensorFlow 1.15.2 and Python 3.6.8.

The script is reco_utils/dataset/sequential_reviews.py which will be automatically excuted when there exists no pre-processed training file.

To train our model on Kuaishou dataset (with default hyper-parameters):

python examples/00_quick_start/sequential.py --dataset kuaishou

or on Taobao dataset:

python examples/00_quick_start/sequential.py --dataset taobao

The implemention is based on Microsoft Recommender.
