我目前正在尝试构建一个包含一些pylab数字的简单应用程序。我刚开始使用，quickly并且担心一些导入问题。也就是说，所有matplotlib后端都将无法工作。
更具体地说，如果以下任何import语句在我的主文件中未注释，quickly则将无法运行该应用程序
#from matplotlib.backends.backend_gtk import FigureCanvasGTK as FigureCanvas
#from matplotlib.backends.backend_gtkagg import FigureCanvasGTKAgg as FigureCanvas
#from matplotlib.backends.backend_gtkcairo import FigureCanvasGTKCairo as FigureCanvas
所以我无法嵌入情节。
这是quickly runif的backend_gtk注释的输出
/usr/lib/python2.7/dist-packages/gobject/constants.py:24: Warning: g_boxed_type_register_static: assertion `g_type_from_name (name) == 0' failed import gobject._gobject
/usr/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py:40: Warning: specified class size for type `PyGtkGenericCellRenderer' is smaller than the parent type's `GtkCellRenderer' class size from gtk import
_gtk
/usr/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py:40: Warning: g_type_get_qdata: assertion `node != NULL' failed from gtk import _gtk
有什么想法可以解决问题吗？你需要更多信息？
您需要使用matplotlib的至少1.2.0版本，然后使用GTK3后端。
取自http://matplotlib.org/examples/user_interfaces/embedding_in_gtk3.html的示例
#!/usr/bin/env python
"""
demonstrate adding a FigureCanvasGTK3Agg widget to a Gtk.ScrolledWindow

"""
from gi.repository import Gtk
from matplotlib.figure import Figure
from numpy import arange, sin, pi
from matplotlib.backends.backend_gtk3agg import FigureCanvasGTK3Agg as FigureCanvas
win = Gtk.Window()
win.connect("delete-event", Gtk.main_quit )
win.set_default_size(400,300)
win.set_title("Embedding in GTK")
f = Figure(figsize=(5,4), dpi=100)
a = f.add_subplot(111)
t = arange(0.0,3.0,0.01)
s = sin(2*pi*t)
a.plot(t,s)
sw = Gtk.ScrolledWindow()
win.add (sw)
# A scrolled window border goes outside the scrollbars and viewport
sw.set_border_width (10)
canvas = FigureCanvas(f) # a Gtk.DrawingArea
canvas.set_size_request(800,600)
sw.add_with_viewport (canvas)
win.show_all()
Gtk.main()
注意：Ubuntu 12.04在存储库中没有Matplotlib 1.2.0，但是可以通过pip以下方式安装：
sudo pip install matplotlib
