Wrong shown version of Astropy

Description

The version of astropy shown is different with different command line. I have carefully checked the environment, and I think this might be a bug of Astropy. And it sometimes causes errors when other packages have dependence on Astropy.

I use the following command lines in Jupyter Notebook:

>>> !pip show astropy
Name: astropy
Version: 5.1
Summary: Astronomy and astrophysics core library
Home-page: http://astropy.org/
Author: The Astropy Developers
Author-email: [e-mail]
License: BSD 3-Clause License
Location: /home/duhc/anaconda3/lib/python3.9/site-packages
Requires: packaging, numpy, PyYAML, pyerfa
Required-by: sdss-marvin, photutils, mgefit, gwcs

>>> import astropy
>>> print(astropy.__version__)
>>> print(astropy.__path__)
4.3.1
['/home/duhc/anaconda3/lib/python3.9/site-packages/astropy']

Expected & Actual behavior behavior

We can see, the address of the astropy shown are the same, both are in /home/duhc/anaconda3/lib/python3.9/site-packages/, while the version of the astropy is different, 5.1 vs 4.3.1.

@pllim Yes. I have checked that the problem is from the Astropy version embedded in Anaconda, when I use Miniconda instead problem will be solved.

Glad you found the cause and thanks for reporting back, @dutry !
