Ошибка при импорте pylab в python 2.6.6

Question

Я пытаюсь импортировать pylab с использованием Python 2.6.6 на REHL 6.4.

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

Я получаю ошибку:

# ./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/pyplot.py", line 78, in <module> 
    new_figure_manager, draw_if_interactive, show = pylab_setup() 
    File "/usr/lib64/python2.6/site-packages/matplotlib/backends/__init__.py", line 25, in pylab_setup 
    globals(),locals(),[backend_name]) 
    File "/usr/lib64/python2.6/site-packages/matplotlib/backends/backend_gtkagg.py", line 10, in <module> 
    from matplotlib.backends.backend_gtk import gtk, FigureManagerGTK, FigureCanvasGTK,\ 
    File "/usr/lib64/python2.6/site-packages/matplotlib/backends/backend_gtk.py", line 8, in <module> 
    import gtk; gdk = gtk.gdk 
    File "/usr/lib64/python2.6/site-packages/gtk-2.0/gtk/__init__.py", line 64, in <module> 
    _init() 
    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 

Все scipy, numpy и matplotlib установлены, но я до сих пор не может импортировать pylab. Есть ли проблема в том, как я импортирую pylab?

Answer 1

исправляются:

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