loss.cpu().data.numpy() is not a list

[londumas]

I might be because of the newest version of pytorch or something else, but loss.cpu().data.numpy() is no longer a list and thus should be changed.

Before:

https://github.com/Alexander-H-Liu/MalConv-Pytorch/blob/939cb59ff1338dbc2b71a186f03bbc677b05c408/train.py#L151

https://github.com/Alexander-H-Liu/MalConv-Pytorch/blob/939cb59ff1338dbc2b71a186f03bbc677b05c408/train.py#L183

Now

history['tr_loss'].append(loss.cpu().data.numpy())

history['val_loss'].append(loss.cpu().data.numpy())
