How to solve "IndexError: too many indices for array"?

[fuzihaofzh]

I have encountered the problem "IndexError: too many indices for array". Is it related to the dataset I use? I just download this file (https://github.com/brendenlake/omniglot/blob/master/python/images_evaluation.zip) and put it under data. The log is as follows:

./train-omniglot-5way-1shot.sh

Hello there,

I have experienced the same error before. To get rid of it, change the line loss += l.data.cpu().numpy()[0] to loss += l.data.cpu().numpy().

I hope this helps,

Best Regards, Simphiwe.
