Bug summary
I get MatplotlibDeprecationWarning when putting the default rcParams copied by matplotlib.rcParams.copy() into matplotlib.rcParams.update().
Code for reproduction
>>> import matplotlib
>>> matplotlib.__version__
'3.0.2'
>>> rc_params = matplotlib.rcParams.copy()
>>> matplotlib.rcParams.update(rc_params)
/Users/xxxx/.local/share/virtualenvs/xxxx/lib/python3.6/site-packages/matplotlib/__init__.py:855: MatplotlibDeprecationWarning:
examples.directory is deprecated; in the future, examples will be found relative to the 'datapath' directory.
"found relative to the 'datapath' directory.".format(key))
/Users/xxxx/.local/share/virtualenvs/xxxx/lib/python3.6/site-packages/matplotlib/__init__.py:846: MatplotlibDeprecationWarning:
The text.latex.unicode rcparam was deprecated in Matplotlib 2.2 and will be removed in 3.1.
"2.2", name=key, obj_type="rcparam", addendum=addendum)It is because matplotlib.rcParams.copy() returns dictionary of rcParams and it includes deprecated rcParams like examples.directory and text.latex.unicode. However, examples.directory and text.latex.unicode are included in the default rcParams of matplotlib.
Expected outcome
Do not show MatplotlibDeprecationWarning for default rcParams.
