timegan-pytorch

This repository holds the code for the reimplementation of TimeGAN (Yoon et al., NIPS2019) using PyTorch. Some of the code was derived from the original implementation here.

⚠️ WARNING!!!

  • This implementation is written for other purposes, not for experiments in the original paper.
  • There are some known issues that I've haven't got time to resolve (see issue #1).

Getting Started

Installing Requirements

This implementation assumes Python3.8 and a Linux environment with a GPU is used.

cat requirements.txt | xargs -n 1 pip install --upgrade
