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\\matplo

Answer 1

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

import warnings

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

Answer 2

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)

Answer 3

you can temporarily suppress a warning, when importing

import warnings

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

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

Answer 4

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

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