Python/matplotlib : getting rid of matplotlib.mpl warning
Question: I am using matplotlib using python 3.4. When I start my program, I have the
following warning message:

    
    
    C:\Python34-32bits\lib\site-packages\matplotlib\cbook.py:123: MatplotlibDeprecationWarning: The matplotlib.mpl module was deprecated in version 1.3. Use `import matplotlib as mpl` instead. warnings.warn(message, mplDeprecation, stacklevel=1)
    

As far as I know I do not use mpl, and all my imports concerning matplotlib
are:

    
    
    import matplotlib.pyplot as plt
    import matplotlib.animation as animation
    

Anything I should do ?


Answer: You can suppress that particular warning, which is probably the preferred way:

    
    
    import warnings
    import matplotlib.cbook
    warnings.filterwarnings("ignore",category=matplotlib.cbook.mplDeprecation)
