導入Matplotlib.pyplot：DLL加載失敗

Question

嘗試導入matplotlib.pyplot（在Spyder中）時，出現以下錯誤：

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.

如果嘗試再次導入，則會得到以下信息：

>>> 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)] 

我猜測這是我的防病毒軟件（Avast）的誤報，盡管我將其關閉后仍然遇到第二個錯誤。 重新安裝模塊或Anaconda均無效。

我的防病毒軟件可能會不斷刪除DLL，如果這樣，是否有阻止它刪除的方法？ 還是我的問題完全是其他問題？

非常感謝！

我在Avast和matplotlib中遇到了完全相同的問題。 我的解決方案是卸載Anaconda，然后重新安裝相同版本，並將C：\\ Anaconda3添加到Avast中的例外掃描目錄中。
