Building GLOW (https://github.com/pytorch/glow 8) is extreme pain which also includes additional pain of building custom llvm (https://solarianprogrammer.com/2013/01/17/building-clang-libcpp-ubuntu-linux/ 1). I am still trying to build GLOW first I find issue with libpng&zlib next I have problem with protobuf. Are your suggestion simple?
