[Django]-Import error when dockerizing a project using zerorpc in python

The traceback shows that zerorpc 0.4.4 is trying to import gevent.coreos, which was removed in gevent 1.2.

Eventually, you want to upgrade zerorpc to a newer version that doesn’t try to import gevent.coreos, but that may require further dependency/code changes.

A more minimal change would be to try installing gevent<1.2 instead.
