matplotlib gtk問題

Question

首先，我對Python，Xwindows，Matplotlib或GTK知之甚少。我正在嘗試運行一個名爲SpliceGrapher的工具，它使用上述工具。我得到一個（醜，不好意思）錯誤：

/usr/lib64/python2.6/site-packages/gtk-2.0/gtk/__init__.py:57: GtkWarning: could not open display 
warnings.warn(str(e), _gtk.Warning) 
/home/my/bin/lib64/python2.6/site-packages/matplotlib/backends/backend_gtk.py:52: GtkWarning: gdk_cursor_new_for_display: assertion `GDK_IS_DISPLAY (display)' failed 
cursors.MOVE   : gdk.Cursor(gdk.FLEUR), 
Traceback (most recent call last):

new_figure_manager, draw_if_interactive, _show = pylab_setup() 
    File "/home/my/bin/lib64/python2.6/site-packages/matplotlib/backends/__init__.py", line 25, in pylab_setup

    File "/home/my/bin/lib64/python2.6/site-packages/matplotlib/backends/backend_gtk.py", line 52, in <module> 
    cursors.MOVE   : gdk.Cursor(gdk.FLEUR), 
    RuntimeError: could not create GdkCursor object 

如果任何人有任何想法，我能做些什麼，那將是巨大的。

我在一臺Linux（RedHat）系統上，通過使用Xming的puTTy。我配置了X11，xeyes顯示了跟隨我的鼠標的小眼睛，所以我知道這是工作。

新的錯誤：

/usr/lib64/python2.6/site-packages/gtk-2.0/gtk/__init__.py:57: GtkWarning: could not open display 

告訴您腳本沒有您的X會話的接入。

你可以在這裏發佈你的腳本嗎？

您是否使用ssh -XC ...訪問機器？

關於shell當你發出echo $DISPLAY你看到了什麼？
當你添加你的腳本print os.getenv("DISPLAY")你看到相同的結果嗎？

還有一個注意事項...我不知道Xming但我可以推薦你嘗試MobaXterm，它有一個內置的ssh和X11服務器編譯的Windows，我的猜測是它可以解決你的X問題。
