    What version of pytorch did you use?

    Hi,moskomule! Great work! I want to know what version of pytorch did you use? Because I can't reproduce your results. I am wondering if the problem appeared on the version of pytorch.

    Hi: I also want to implement the EWC in pytorch by myself. But according to the Counterpart Tensorflow implementation: https://github.com/ariseff/overcoming-catastrophic/blob/master/experiment.ipynb their accuracy is so high. Why does the Pytorch implementation has only 0.7 in your implementation. Many thanks Shixian Wen

    question for the formular in _diag_fisher() function

    Hello, I have read your code and it is really helpful for me to understand the logic of EWC. I still have a doubt for the input of nll_loss in _diag_fisher function. Should the label be the ground truth, not the output of the model? Thanks for your code again and looking forward to your answer!
