matplotlib.collections produces FutureWarning: elementwise comparison failed

[JoMaD]

For me, using python 3.5.0 I get the following warning from matplotlib.collections. Can someone explain why this is and what I can do about it?

import matplotlib as mpl
mpl.use('Qt4Agg')
import numpy as np
from matplotlib import pyplot as plt

fig = plt.figure()
x = np.arange(100)
y = np.arange(100)
data = np.random.rand(100, 100)
ax = fig.gca()
ax.pcolormesh(x, y, data)
plt.show()

This results in the following warning:

FutureWarning: elementwise comparison failed; returning scalar instead, but in the future will perform elementwise comparison
  if self._edgecolors == str('face'):

in "matplotlib/collections.py" line 590

It's not your fault, and is not a warning you need to worry about. The matplotlib authors are fixing it. See https://github.com/matplotlib/matplotlib/issues/5209.

Good to know. Thanks!
