Matplotlib Pyplot在Ubuntu 16.04上中断

Question

I am currently using Python 2.7 on Ubuntu 16.04 and would like the ability to plot figures using Matplotlib. However, calling any sort of plot command causes the entire script to hang at that line.

** Note ** Before marking this as a duplicate question, please consider that this issue may not be related to the backend that I am using as I have tried every iteration of this solution that I have found on the internet.

A simple script which illustrates my problem:

#!/usr/bin/env python
import matplotlib
matplotlib.use('TkAgg')
from matplotlib import pyplot as plt
plt.interactive('True')


if __name__ == '__main__':

    print 'Hello World!'
    plt.figure()
    print 'Hello Again World!'

The output of the above script is: Hello World!

The script then hangs at the plt.figure() line, causes 100% cpu usage, and cannot be killed using Ctrl-C. I use "kill" to kill that process.

Answer 1

I never figured out what caused my problem, but my (poor) solution was to reinstall Ubuntu 16.04 and then matplotlib. It is working fine now.

Thanks everyone!
