This issue seems to be reported a few times on various githubs projects. I've also reproduced using a brew install of python 2.7.15. I haven't been able to reproduce with python 3.6. Note this requires a framework build of python.

Background on the underlying issue cause due to a change in high Sierra

The work around seems to be setting an environment variable OBJC_DISABLE_INITIALIZE_FORK_SAFETY prior to executing python.
