Bug report

matplotlib (1.4.x and 2.0.0) make 300% CPU usage after import

• I am using matplotlib on the Raspberry Pi (raspbian jessie - nu GUI). Once I import anything from the library, the CPU goes to 300%. It does not matter if I select any specific backend.

Code for reproduction

import matplotlib

Matplotlib version

• Raspbian Jessie, 1.4.x or 2.0.0

• Python 2.7 and Python 3

• I installed it with

  sudo apt-get install python-matplotlib

or

sudo pip install matplotlib
