MacOS import TRMF error

[AbdullahO]

I followed the python installation instruction on my MacOS, and everything seemed to run smoothly. When I try to import TRMF, I get the following error:

rm -rf trmf trmf*.so *.o

Please follow https://github.com/rofuyu/exp-trmf-nips16/tree/master/python#install-for-macos. It requires GCC to build the library (instead of the built-in clang). The error msg suggests that you might still use the clang to build the package. Please try to set the environment variables appropriately to install it on Mac.
