matplotlib.pyplot的導入錯誤

Question

我看到了類似的帖子，但是當我嘗試運行import matplotlib.pyplot as plt時給出的錯誤是不同的：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/jhn545/miniconda2/lib/python2.7/site-packages/matplotlib/pyplot.py", line 115, in <module>
    _backend_mod, new_figure_manager, draw_if_interactive, _show = pylab_setup()
  File "/home/jhn545/miniconda2/lib/python2.7/site-packages/matplotlib/backends/__init__.py", line 32, in pylab_setup
    globals(),locals(),[backend_name],0)
  File "/home/jhn545/miniconda2/lib/python2.7/site-packages/matplotlib/backends/backend_qt5agg.py", line 16, in <module>

    import matplotlib.backends.qt_editor.figureoptions as figureoptions
  File "/home/jhn545/miniconda2/lib/python2.7/site-packages/matplotlib/backends/qt_editor/figureoptions.py", line 20, in <module>
    import matplotlib.backends.qt_editor.formlayout as formlayout
  File "/home/jhn545/miniconda2/lib/python2.7/site-packages/matplotlib/backends/qt_editor/formlayout.py", line 56, in <module>
    from matplotlib.backends.qt_compat import QtGui, QtWidgets, QtCore
  File "/home/jhn545/miniconda2/lib/python2.7/site-packages/matplotlib/backends/qt_compat.py", line 128, in <module>
    from PyQt5 import QtCore, QtGui, QtWidgets
ImportError: libQt5Core.so.5: object file has no loadable segments

我正在使用miniconda2，並且已經嘗試卸載並重新安裝matplotlib

謝謝@SiHa。 Set Matplotlib Backend上的帖子效果很好。

該帖子的答案之一還提供了有關如何設置默認后端的有用信息。 只需轉到您的matplotlibrc文件（我的文件位於miniconda2/lib/python2.7/site-packages/matplotlib/mpl-data/matplotlibrc ），然后更改backend變量。
