Question

我想在我的python脚本中使用matplotlib来显示一些图形。但每当我打电话给它时，我都会收到错误

AttributeError: get_content_extents

MWE：

>>> import matplotlib
>>> from matplotlib import pyplot as plt
>>> def a(x):
...     return x*x
... 
>>> import numpy as np
>>> d = np.linspace(0, 10, 2**12)
>>> plt.plot(d, a(d))
Gtk-Message: Failed to load module "pantheon-filechooser-module"
[<matplotlib.lines.Line2D object at 0x7f1edc44d350>]
>>> plt.show()

结果是：回溯（最近一次调用最后一次）：

  File "/usr/local/lib/python2.7/dist-packages/matplotlib/backends/backend_qt5agg.py", line 176, in __draw_idle_agg
    FigureCanvasAgg.draw(self)
  File "/usr/local/lib/python2.7/dist-packages/matplotlib/backends/backend_agg.py", line 469, in draw
    self.renderer = self.get_renderer(cleared=True)
  File "/usr/local/lib/python2.7/dist-packages/matplotlib/backends/backend_agg.py", line 486, in get_renderer
    self.renderer = RendererAgg(w, h, self.figure.dpi)
  File "/usr/local/lib/python2.7/dist-packages/matplotlib/backends/backend_agg.py", line 99, in __init__
    self._update_methods()
  File "/usr/local/lib/python2.7/dist-packages/matplotlib/backends/backend_agg.py", line 134, in _update_methods
    self.get_content_extents = self._renderer.get_content_extents
AttributeError: get_content_extents

如果我尝试使用

更改后端，也会发生同样的情况

plt.switch_backend('qt4agg')

在尝试gtk后端（＆＃39; gtkagg＆＃39;）时，我得到了

/usr/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py:127: RuntimeWarning: PyOS_InputHook is not available for interactive use of PyGTK
  set_interactive(1)

我该怎么做才能解决这个问题？

绘图时，Matplotlib会抛出AttributeError：get_content_extents
