A PyTorch Extension: Tools for easy mixed precision and distributed training in Pytorch

This repository holds NVIDIA-maintained utilities to streamline mixed precision and distributed training in Pytorch. Some of the code here will be included in upstream Pytorch eventually. The intention of Apex is to make up-to-date utilities available to users as quickly as possible.

How to use this bert version to use the pretrianed model?

Hi guys, thanks for great work. I'm trying to use this pytorch version protein-bert to use the pre-trained model 'ftp://ftp.cs.huji.ac.il/users/nadavb/protein_bert/epoch_92400_sample_23500000.pkl', but have no clues at all. Could you please give some suggestions? Thank you so much!
