    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!
