Could not find or load the Qt platform plugin "xcb"

Question

On my OS(Linux Mint Debian Edition 2), except for the system python(/usr/bin/python) installed by the apt, I also installed the anaconda. But I've encounterd a problem running the following code with the anaconda python

# test.py import matplotlib.pyplot as plt import numpy as np x = np.array([0, 1]) plt.scatter(x, x) plt.show() 

The error is

This application failed to start because it could not find or load the Qt platform plugin "xcb".

Reinstalling the application may fix this problem.

Aborted

But if I try with the system python, i.e., /usr/bin/python test.py, it works correctly.

Then I tried the ipythons, of system and of anaconda, the result is same as before: the anaconda ipython kernel died.

And I tried add the ipython magic %matplotlib inline into the code, the anaconda ipython works correctly now. But if I replace the %matplotlib inline with %pylab, the anaconda ipython died again.

Note: I use the python 2.7. System ipython's version is 2.3, anaconda ipython's version is 3.2.

Same problem with Linux Mint 17, 64 bit. It was solved after 4h searching on the net! You need to give these commands on the terminal from folder /anaconda2/bin

sudo ./conda remove qt sudo ./conda remove pyqt sudo ./conda install qt sudo ./conda install pyqt 

Hope it helps!
