导入Matplotlib.pyplot：DLL加载失败

Question

尝试导入matplotlib.pyplot（在Spyder中）时，出现以下错误：

Python 3.5.1 |Anaconda 2.5.0 (64-bit)| (default, Jan 29 2016, 15:01:46) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import sympy as sp
>>> import numpy as np
>>> import matplotlib.pyplot as plt
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\...\Anaconda3_1\lib\site-packages\matplotlib\pyplot.py", line 36, in <module>
    from matplotlib.figure import Figure, figaspect
  File "C:\Users\...\Anaconda3_1\lib\site-packages\matplotlib\figure.py", line 35, in <module>
    from matplotlib import _image
ImportError: DLL load failed: Operation did not complete successfully because the file contains a virus or potentially unwanted software.

如果尝试再次导入，则会得到以下信息：

>>> import matplotlib.pyplot as plt
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\...\Anaconda3_1\lib\site-packages\matplotlib\pyplot.py", line 36, in <module>
    from matplotlib.figure import Figure, figaspect
  File "C:\Users\...\Anaconda3_1\lib\site-packages\matplotlib\figure.py", line 35, in <module>
    from matplotlib import _image
  File "C:\Users\...\Anaconda3_1\lib\site-packages\matplotlib\_image.py", line 7, in <module>
    __bootstrap__()
  File "C:\Users\...\Anaconda3_1\lib\site-packages\matplotlib\_image.py", line 6, in __bootstrap__
    imp.load_dynamic(__name__,__file__)
  File "C:\Users\...\Anaconda3_1\lib\imp.py", line 342, in load_dynamic
    return _load(spec)
ImportError: DLL load failed: The specified module could not be found.

我的Python版本如下：

Python 3.5.1 |Anaconda 2.5.0 (64-bit)| (default, Jan 29 2016, 15:01:46) [MSC v.1900 64 bit (AMD64)] 

我猜测这是我的防病毒软件（Avast）的误报，尽管我将其关闭后仍然遇到第二个错误。 重新安装模块或Anaconda均无效。

我的防病毒软件可能会不断删除DLL，如果这样，是否有阻止它删除的方法？ 还是我的问题完全是其他问题？

非常感谢！

我在Avast和matplotlib中遇到了完全相同的问题。 我的解决方案是卸载Anaconda，然后重新安装相同版本，并将C：\\ Anaconda3添加到Avast中的例外扫描目录中。
