Trouble importing gala.coordinates #138

Closed HBuenoo closed 5 years ago

HBuenoo commented 5 years ago

Hi, I do have scipy installed, as I run:

pip install scipy Requirement already satisfied: scipy in ./anaconda3/lib/python3.7/site-packages (1.1.0)

But when I try to:

from gala import coordinates as gc

All I get is:

ModuleNotFoundError Traceback (most recent call last)

Hi! It looks like you installed the development version of gala - that's fine, but just an FYI that it may contain less tested functionality :).

In this particular case, I think the issue is your version of scipy. The dev version of gala requires scipy >= 1.2, so try updating scipy with pip install --upgrade scipy and then try importing gala again.
