Hi @janilbols,

I wasn't able to reproduce this error. Could you send me the output of pip list on your machine?

Problem solved after changing the script 'eth_mnist.py' line 113 to 116:

accuracy['all'].append(100 * torch.sum(labels[i - update_interval:i].long() \
                                               == all_activity_pred).data.tolist() / update_interval)
accuracy['proportion'].append(100 * torch.sum(labels[i - update_interval:i].long() \
                                               == proportion_pred).data.tolist() / update_interval)

The torch.sum returns a tensor, which can't be operate by numpy. Use .data.tolist() to convert tensor to list, which works.
