Hi, Andrew

As I run your code, there prints a RuntimeError: 'volatile can only be set on leaf variables' in line 44 of train.py

self.backprop_grads[name].volatile = False

could you check it out?

Thanks

Same problem any solutions?

adding the following seems to make it work: if self.backprop_grads[name].grad_fn == None: self.backprop_grads[name].volatile = False However there are still other issues

will check it these days, I doubt that it's about the version of pytorch since this error didn't appear before.
