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 mplinstead. 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 ?

The last, Agg, is a non-interactive backend that can only write to files. It is used on Linux, if Matplotlib cannot connect to either an X display or a Wayland display.
What Does Matplotlib Mean? Matplotlib is a plotting library available for the Python programming language as a component of NumPy, a big data numerical handling resource. Matplotlib uses an object oriented API to embed plots in Python applications.
The matplotlib. pyplot is a collection of functions that make matplotlib work like MATLAB. Each pyplot function makes some change to a figure: e.g., creates a figure, creates a plotting area in a figure, plots some lines in a plotting area, decorates the plot with labels, etc.
You can suppress that particular warning, which is probably the preferred way:
import warnings
import matplotlib.cbook
warnings.filterwarnings("ignore",category=matplotlib.cbook.mplDeprecation)
you can temporarily suppress a warning, when importing
import warnings
def fxn():
warnings.warn("deprecated", DeprecationWarning)
with warnings.catch_warnings():
warnings.simplefilter("ignore")
fxn()
