Libtorch is slower on Windows. Also, can't compile with MKLDNN

I’ve tried building the latest and it seems to be completing further. It doesn’t compile every time it seems but generally it can make it to end of caffe2. I am getting the following error when I try to import torch.

The following is the kdiff between torch/lib in a working (python installed version) vs master installed via python setup.py install.

would appreciate any advice.

Thanks,
Nick
