I cannot use the pytorch that was built successfully from source: (DLL) initialization routine failed. Error loading caffe2_detectron_ops_gpu.dll

The error is caused by our poor support for MSVC OpenMP in detectron. Please build with MKL so Intel OpenMP will be used. See https://pytorch.org/docs/stable/notes/windows.html#include-optional-components.
