RuntimeError: invalid argument 0: Sizes of tensors must match except in dimension 1. Got 111 and 112 in dimension 2 at /opt/conda/conda-bld/pytorch_1525909934016/work/aten/src/THC/generic/THCTensorMath.cu:111

Hello, I try your code and I encountered this error above.
I added the ceil_mode=True but it doesn't work.
