在CentOS中安装matplotlib（使用命令yum install python-matplotlib)后，在试图导入pyplot后报错：

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
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 11, in <module>
raise ImportError("Gtk* backend requires pygtk to be installed.")
ImportError: Gtk* backend requires pygtk to be installed.

此时可以这样解决：

import matplotlib

matplotlib.use('Agg')

from matplotlib.pyplot import *
