Warning on 04.11 Customizing Matplotlib - Configurations and Stylesheets

[LeonLrz]

When I want to run the codes below

# reset rcParams
plt.rcParams.update(IPython_default);

I got those warning D:\Anaconda3\lib_collections_abc.py:841: MatplotlibDeprecationWarning: The examples.directory rcparam was deprecated in Matplotlib 3.0 and will be removed in 3.2. In the future, examples will be found relative to the 'datapath' directory. self[key] = other[key] D:\Anaconda3\lib_collections_abc.py:841: MatplotlibDeprecationWarning: The savefig.frameon rcparam was deprecated in Matplotlib 3.1 and will be removed in 3.3. self[key] = other[key] D:\Anaconda3\lib_collections_abc.py:841: MatplotlibDeprecationWarning: The text.latex.unicode rcparam was deprecated in Matplotlib 3.0 and will be removed in 3.2. self[key] = other[key] D:\Anaconda3\lib_collections_abc.py:841: MatplotlibDeprecationWarning: The verbose.fileo rcparam was deprecated in Matplotlib 3.1 and will be removed in 3.3. self[key] = other[key] D:\Anaconda3\lib_collections_abc.py:841: MatplotlibDeprecationWarning: The verbose.level rcparam was deprecated in Matplotlib 3.1 and will be removed in 3.3. self[key] = other[key]

How should I fix this problem?
