【问题描述】：
我正在尝试运行以前运行的应用程序。它曾经在 Ubuntu 和 Windows 7 上运行。我现在有一台 Windows 10 机器，但代码失败了。可能是因为我现在使用的是 python 3.5，但坦率地说，我不记得我在其他机器上使用了什么（这些机器不再可用）。
重点是：
import matplotlib
matplotlib.use("TkAgg")
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2TkAgg
前段时间已从各个地方取出。但是，现在当我运行它时，它会抛出一个错误：
Traceback (most recent call last):
File "C:\....py", line 17, in <module>
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2TkAgg
File "C:\Users\...\AppData\Local\Programs\Python\Python35-32\lib\site-packages\matplotlib\backends\backend_tkagg.py", line 13, in <module>
import matplotlib.backends.tkagg as tkagg
File "C:\Users\g...\AppData\Local\Programs\Python\Python35-32\lib\site-packages\matplotlib\backends\tkagg.py", line 9, in <module>
from matplotlib.backends import _tkagg
ImportError: DLL load failed: The specified module could not be found.
在交互式会话中，似乎是第三行失败了：
>>> import matplotlib
>>> matplotlib.use("TkAgg")
>>> from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2TkAgg
Traceback (most recent call last):
File "<pyshell#4>", line 1, in <module>
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2TkAgg
File "C:\Users\...\AppData\Local\Programs\Python\Python35-32\lib\site-packages\matplotlib\backends\backend_tkagg.py", line 13, in <module>
import matplotlib.backends.tkagg as tkagg
File "C:\Users\...\AppData\Local\Programs\Python\Python35-32\lib\site-packages\matplotlib\backends\tkagg.py", line 9, in <module>
from matplotlib.backends import _tkagg
ImportError: DLL load failed: The specified module could not be found.
我试过了
pip uninstall matplotlib
pip install matplotlib
在命令提示符下，但错误仍然存在。
好像有python-matplotlib-tk包，但我不确定这是什么。
我应该退回到 python 3.4，还是有解决方案？这是一个已知问题吗？
针对以下关于安装 matplotlib 的评论：

这里是一个在 python 3.4 中使用这种方法的教程的链接：here

你是如何安装 matplotlib 的？都编译正确了吗？
-
@MattDMo，是的。请参阅问题中的点子报告
-
哦，对了，我忘了 PyPI 上有 Windows 轮子。下一个问题：你能成功
import tkinter吗？ -
我将尝试回到 python 3.4。看来我还需要 Microsoft Visual C++ 10.0，它（据我所知）是 Visual Studio Community 2015。我现在正在安装它。其他人说尝试从sourceforge 安装numpy，我可能会尝试下一个。
