CUDA Error

Hello @JiaxuanYou,

When I ran python3 main.py. I got the following message even after run all installations commands.

Hello again,

I changed 'self.cuda = 1' to 'self.cuda = 0' in args.py. But I got other error:

I believe it is a version problem, you can change the loss.data[0] to loss.item(), and then the test code can run.
