I've been trying to install a particular package - datashader . Steps followed -
> python -m venv dashshader #my spelling mistake wrote data->dash
> cd dashshader
> Scripts\activate.bat
(dashshader) > conda install datashader
# list of packages to be downloaded ...
# Package to be installed datashader:0.6.6-py36_1
# list of packages to be updated ...
# The following will be downgraded:
anaconda: custom-py37_0 --> custom-py36h363777c_0
python: 3.7.0-hea74fb7_0 --> 3.6.7-h33f27b4_1
Based on above downgrade info I assumed my python will be downgraded in this virtual environment. But that didn't happen.
(dashshader) > conda list listed all the packages above including dashshader. Yet when I did import pandas as pd it failed. Also (dashshader) > python --version #3.7.0-hea74fb7_0.
But when I made a new env and did
(newenv) > pip install datashader , another bunch of packages installed, and python --version is #Python 3.6.7 :: Anaconda custom and my package imports are good.
When I do pip list in the older enivronment, I get an AssertionError: SRE Module mismatch. Although my problem is solved with pip; I have very little idea about what's going on. Clearly conda took up some immutable space related to sre_compile.py But I don't understand why it didn't downgrade Python after saying it will downgrade python.
