Can't import rcParams from colors.py #16386
Description
On master, clean conda install, with a pip -e install . to get the development version, if I add:
from matplotlib import rcParams to the top of colors.py, I get an error
Traceback (most recent call last):
File "testImport.py", line 1, in <module>
import matplotlib.pyplot as plt
File "/Users/jklymak/matplotlib/lib/matplotlib/__init__.py", line 106, in <module>
from . import cbook, rcsetup
File "/Users/jklymak/matplotlib/lib/matplotlib/rcsetup.py", line 31, in <module>
from matplotlib.colors import is_color_like
File "/Users/jklymak/matplotlib/lib/matplotlib/colors.py", line 68, in <module>
from matplotlib import rcParams
ImportError: cannot import name 'rcParams' from 'matplotlib' (/Users/jklymak/matplotlib/lib/matplotlib/__init__.py)
(FWIW, I don't want to do this, I really want to do import matplotlib.scale as mscale but it throws the same error inside scale.py, so the is the simplest reproducible error).
The other cases where folks have seen this (#1280, #12983, #13407, #15353) have seemed to be cases where there was a name clash. Bit this is a pretty clean install, so I don't think thats the issue.
