Hi, Thank you for my inspiration for the BERT QA. I'm trying custom training at # 307. The following error occurs when the "reader.fit (X = (train_examples, train_features))" statement is executed.

AttributeError: 'tuple' object has no attribute 'backward'

Hi,

I just merged the branch with the fix for the training.

Could you please try with the latest version of cdQA?

Thanks!

Pytorch has problems when installing with "torch> = 1.2.0" listed in "requirements.txt". Installing Pytorch separately solved the problem.

Thanks a lot for fast replying.
