loss.backward() NotImplementedError #57

Closed XuechaoChen closed 3 years ago

XuechaoChen commented 3 years ago

When I run "loss.backward()", there's a "NotImplementedError" occured:

Traceback (most recent call last): File "train_cylinder_asym.py", line 168, in main(args) File "train_cylinder_asym.py", line 136, in main loss.backward() ...... torch/autograd/function.py", line 181, in backward raise NotImplementedError NotImplementedError

Appreciate anyone's help.
