Update on 22nd Sept: We have made improvements to this work and achieved much better performance and efficiency! Check our the latest version of this work at https://arxiv.org/abs/2103.11731v3. Codes will be released in Oct 2021.
Update on 31st Oct: Codes released. However, we are rushing an important deadline, so codes might still be a bit messy. We will release the cleaned-up codes, pre-trained models, logs, and detailed instruction in early Dec 2021.
Environment: Ubuntu 18.04 LTS Python 3.7 Pytorch 1.7.1 Cuda 10.2
