Pytorch 1.2.0: Not Implemented Error #8

Closed meshiang closed 5 years ago

meshiang commented 5 years ago

Hello, I am currently running Pytorch 1.2.0 with Cuda 9.2 and Python 3.7, but it seems I ran into "NotImplementedError" for all unittest results. Can anyone provide any solutions?

I ran python test_pac.py and here is the results. 

E.E/home/pc3387/Desktop/Reference/pacnet/pac.py:447: UserWarning: To copy construct from a tensor, it is recommended to use sourceTensor.clone().detach() or sourceTensor.clone().detach().requires_grad_(True), rather than torch.tensor(sourceTensor).
  output = output / (norm + torch.tensor(empty_mask, dtype=input.dtype, device=input.device))
.EE.EEEEEEEEE.EEEE

meshiang commented 5 years ago

Update: This issue seems to exist because Pytorch 1.2 no longer provide open THNN API for the function Im2Col_updateGradInput. (This particular commit)

Quick Solution: Downgrade to Pytorch 1.1. I do think that the README.md should fixed to only support up to Pytorch 1.1

suhangpro commented 5 years ago

@meshiang Thanks for the information. README is updated accordingly.
