Python 3.8 issues

mentioned in issue bob#266 (closed)

bob.extension: conda build works on the master (https://gitlab.idiap.ch/bob/bob.extension/pipelines/47744), but fails on the nightlies (https://gitlab.idiap.ch/bob/nightlies/-/jobs/222858)

Something is pulling in python-3.7 instead of python-3.8, and this is creating the conflict.

Maybe sphinx?

There are several deps actually that conflict: click-plugins, sphinx_rtd_theme, (maybe nose).

Running each package in isolation works fine. Check bob.extension, bob.blitz, bob.core and bob.io.base. All green with python 3.8

mmmm, bob-devel is pinned to bob-devel=2020.11.18 instead of 2021.01.29, is that correct?

I'm trying to debug locally

I found the issue. It was my fault. Fixed here: nightlies@7a5cd6a7

Great job! I like auto-solved issues ;-)
