pip install hypothesis[pandas] says hypothesis3.82.1 does not provide the extra 'pandas'

Question

When I ran pip install hypothesis[pandas] I got the following:

Collecting hypothesis[pandas] Using cached https://files.pythonhosted.org/packages/36/58/222aafec5064d12c2b6123c69e512933b1e82a55ce49015371089d216f89/hypothesis-3.82.1-py3-none-any.whl hypothesis 3.82.1 does not provide the extra 'pandas'

pip install hypothesis[django] seemed to work and hypothesis.extra has django but not pandas. Any idea what is going on with the pip install for pandas and numpy extras?

Answer 1

fixed my problem with pip install hypothesis[all] and also realizing that hypothesis.extra tab completion only showed django, and that pandas and numpy extras seem to need to be imported explicitly.

Answer 2

Update: Hypothesis 3.82.2 added the metadata to support pip install hypothesis[pandas].

Looks like we simply haven't added it to the setuptools metadata - now tracking via issue 1671 for any first-time contributor who would like to fix it :)

FYI this won't actually add any dependencies though; if you have both Hypothesis and Pandas>0.19 installed the extra will just work!
