I am trying to setup PWCNet for optical flow extraction using PyTorch, from this link: https://github.com/NVlabs/PWC-Net/tree/master/PyTorch 4.
After following the steps in ReadMe it says
ImportError(“torch.utils.ffi is deprecated. Please use cpp extensions instead”)
On this link https://github.com/pytorch/pytorch/issues/15645 5 they say so there is no easy solution to this? it looks like it requires a full revamp of the code that used to work for pytorch <= 0.4.1
But the code is written in PyTorch 0.2
Neither I am able to install cudatoolkit 8.0 using  conda as mentioned in the ReadMe.
