Short description of the problem:
With a fresh install on OSX (stdpopsim-0.2.0-py3-none-any.whl - installing via pip) I get this error

Suggested fixes:
Should scipy be added to requirement/config?

Looking at

stdpopsim/requirements/CI/requirements.txt

Line 18 in d89010f

scipy==1.10.1

I see scipy is mentioned!?

[petrelharp]

Hm - I see that the most recent release (0.2.0) did indeed use scipy but did not have scipy under install_requires in setup.cfg. That was an error, looks like - and I don't know why that didn't get caught by something. Seems like we need an additional installation check in CI somewhere.

However, since then we've removed scipy, so this won't be a problem for the next release?

[petrelharp]

So - I think we can close this, but this can be replaced by #1518?

Thanks @petrelharp !
