When freshly creating an environment on Mac OS X, import torch would error, because:

• torch is installed via pip, which uses its own version of libomp
• Other libraries installed via Conda (e.g. numpy) uses a system-wide libomp, usually LLVM-based

Having different libomp causes errors when running any Python script or notebook using torch. Thus, we force every conda-installed package to not use libomp instead.
