Fehler beim Importieren von pylab in Python 2.6.6

Question

Ich versuche pylab mit Python 2.6.6 auf REHL 6.4 zu importieren.

#!/usr/bin/env python 
import os, zipfile,glob, shutil,time,scipy,numpy,matplotlib 
from pylab import * 

ich den Fehler:

# ./script.py 
Traceback (most recent call last): 
    File "./script.py", line 3, in <module> 
    from pylab import * 
    File "/usr/lib64/python2.6/site-packages/pylab.py", line 1, in <module> 
    from matplotlib.pylab import * 
    File "/usr/lib64/python2.6/site-packages/matplotlib/pylab.py", line 247, in <module> 
    from matplotlib.pyplot import *

    File "/usr/lib64/python2.6/site-packages/matplotlib/backends/backend_gtkagg.py", line 10, in <module>

    File "/usr/lib64/python2.6/site-packages/gtk-2.0/gtk/__init__.py", line 52, in _init 
    _gtk.init_check() 
RuntimeError: could not open display 

Alle scipy, numpy und matplotlib installiert sind, aber ich kann immer noch nicht pylab importieren. Gibt es ein Problem in der Art, wie ich pylab importiere?

Answer 1

mit fixed:

import matplotlib as mpl 
mpl.use('Agg') 
import matplotlib.pyplot as plt
