※ 引述《hardliner (liner)》之銘言：
$HOME=/root
CONFIGDIR=/root/.matplotlib
matplotlib data path
/usr/local/lib/python2.6/site-packages/matplotlib/mpl-data
loaded rc file /root/.matplotlib/matplotlibrc
matplotlib version 0.98.5.2
verbose.level helpful
interactive is False
units is False
platform is linux2
Using fontManager instance from /root/.matplotlib/fontList.cache
backend Agg version v2.2
以上的訊息是我照 manual 上所指示所得到的訊息，下面是我測試的內容。
from pylab import *
plot([1,2,3])
show()
>>> from pylab import *
>>> plot([1,2,3])
[<matplotlib.lines.Line2D object at 0x8bceeac>]
>>> show()
/usr/local/lib/python2.6/site-packages/matplotlib/backends/__init__.py:41:
UserWarning:
Your currently selected backend, 'Agg' does not support show().
Please select a GUI backend in your matplotlibrc file
('/root/.matplotlib/matplotlibrc')
or with matplotlib.use()
(backend, matplotlib.matplotlib_fname()))
由於問題出在 backend，看起來是指 Agg 不支援 show()，而搜尋相關網頁，
只找到一篇是使用 WXAgg（
http://0rz.tw/WcgOw），於是我安裝了 wxPython，
vi ~/.matplotlib/matplotlibrc，更改其內容為下
backend : WXAgg
可是更改之後，卻連 import 都不行了。
>>> from pylab import *
Traceback (most recent call last):

File
"/usr/local/lib/python2.6/site-packages/matplotlib/backends/backend_wxagg.py",
line 19, in <module>
import wx
ImportError: No module named wx
請問問題是出在哪裡呢？謝謝。

謝謝您的回覆，不過我測試了之後出現以下訊息，
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python2.6/site-packages/matplotlib/pyplot.py", line
75, i
new_figure_manager, draw_if_interactive, show = pylab_setup()
File
"/usr/local/lib/python2.6/site-packages/matplotlib/backends/__init__.py",
globals(),locals(),[backend_name])
File
"/usr/local/lib/python2.6/site-packages/matplotlib/backends/backend_tkagg
import Tkinter as Tk, FileDialog
File "/usr/local/lib/python2.6/lib-tk/Tkinter.py", line 39, in <module>
import _tkinter # If this fails your Python may not be configured for Tk
ImportError: No module named _tkinter
這樣是指我需要另外安裝 TkInter 嗎？還是我的 backend 有哪裡出問題了？
謝謝。
