The expanded size of the tensor (4) must match the existing size (32) at non-singleton dimension 1. Target sizes: [32, 4]. Tensor sizes: [32]

Hi, I used pytorch 1.4.0 it raised this error. Any idea where goes wrong?

I think this is an issue with PyTorch version. The code is implemented for 0.4 Thanks!

Did anyone work out? Could somebody help me out? I met an error "stack expects a non-empty TensorList“. I do not know what happened.
