Python3.5 backend_tkagg不再可用？

我試圖運行之前運行的應用程序。它曾經在Ubuntu和Windows 7上運行。我現在有一臺Windows 10機器，代碼失敗。這可能是因爲我現在在python 3.5上，儘管我坦白地記不起其他機器上的內容（這些機器不再可用）。Python3.5 backend_tkagg不再可用？

的主要線路有：

import matplotlib 
matplotlib.use("TkAgg") 
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2TkAgg

已經從各個地方前段時間解除。但是，現在當我運行它，它拋出一個錯誤：

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.

在交互式會話，它似乎是一個的失敗的第三行：

>>> 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.

我試圖

pip uninstall matplotlib 
pip install matplotlib

在命令提示符下，但錯誤仍然存在。

看來可能有一個python-matplotlib-tk包，但我不確定這是什麼。

我應該回到python 3.4，還是有解決方案？這是一個已知的問題嗎？

你是怎麼安裝matplotlib的？這一切是否正確編譯？ – MattDMo

@MattDMo，是的。請參閱問題 –

這是你的問題：

導入錯誤：DLL加載失敗：指定的模塊找不到。

您可以嘗試在類似Dependency Walker的軟件中打開_tkagg.pyd並查找錯誤。

這也有可能是_tkagg.pyd與Python的版本不兼容使用的是

好吧，我已經下載並安裝了Dependency Walker。我在哪裏可以找到_tkagg.pyd？ –

此目錄中的某處：C：\ Users \ ... \ AppData \ Local \ Programs \ Python \ Python35-32 \ lib \ site-packages \ matplotlib \ backends \您是否確定您使用的是32位版本的Python3。 5？ –

好的，所以在那個目錄中沒有_tkagg.pyd文件。有一個名爲_tkadd.cp35-win32.pyd的文件。我運行了Dependency Walker，它確實拋出了一個依賴錯誤 –

建我有同樣的問題

我matplotlib

For Python 3.5 the Visual C++ Redistributable for Visual Studio 2015 needs to be installed. In case Python 2.7 to 3.4 are not installed for all users (not the default), the Microsoft Visual C++ 2008 (64 bit or 32 bit for Python 2.7 to 3.2) or Microsoft Visual C++ 2010 (64 bit or 32 bit for Python 3.3 and 3.4) redistributable packages need to be installed.

閱讀文檔和我安裝了the Visual C++ Redistributable for Visual Studio 2015 它解決了這個問題

爲我修好了。你如何發現它？ – CaTx

是的！謝謝！我正在關注tkinter GUI的[pythonprogramming.net]（https://pythonprogramming.net）教程，並遇到了這個問題。 –

我也是found辦法中導入數據包，使用「導入matplotlib爲MPL」：

 import matplotlib as mpl 
     mpl.use("TkAgg") 
     from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2TkAgg

這工作對我很好，希望它爲他人太（：
