If you suspect this is an IPython bug, please report it at:
    https://github.com/ipython/ipython/issues
or send an email to the mailing list at [e-mail]

You can print a more detailed traceback right now with "%tb", or use "%debug"
to interactively debug it.

Extra-detailed tracebacks for bug-reporting purposes can be enabled via:
    %config Application.verbose_crash=True

This issue arises due to gevent’s monkey-patching of code related to threads (see #2785). TL;DR use the following launcher script for IPython:

#!/usr/bin/env python
import gevent.monkey
gevent.monkey.patch_all()

import IPython
IPython.start_ipython()

Now importing locust should work.

I am wondering how I can configure that in Atom
