Error Training TypeError: 'NoneType' object is not callable

[moldach]

I was able to get my environment setup successfully to run eval; however, now, trying train I'm running into an issue. Not sure if it's a syntax issues or if something else is going on? You help is greatly appreciated.

hello hang,
I've also met the same problem by trying neural style transfer

[zhanghang1989]

The main issue is torchfile doesn't work any more.

You may load VGG weights from other places. e.g. from torchvision

thank you for your replies very much, I will try again:D
