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:Python34-32bitslibsite-packagesmatplotlibcbook.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 ?

Answers:

you can temporarily suppress a warning, when importing

import warnings

def fxn():
    warnings.warn("deprecated", DeprecationWarning)

with warnings.catch_warnings():
    warnings.simplefilter("ignore")
    fxn()

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

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

It would be useful to see the code, however remember to set the parameters of the plot first, only then initialize the plot.

Exemple, what you may have done:

plt.pcolormesh(X, Y, Z)
plt.axes().set_aspect('equal')

What you have to do:

plt.axes().set_aspect('equal')
plt.pcolormesh(X, Y, Z)

I was able to suppress that warning with the code below:

import warnings

warnings.filterwarnings("ignore",category=UserWarning)

Due to

MatplotlibDeprecationWarning: mplDeprecation was deprecated in Matplotlib 3.6 and will be removed two minor releases later ...

use this instead:

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