Keras已安裝但未能正常工作

我正在使用keras with theano作爲後端，在Windows 10上構建神經網絡。我的Python版本爲2.7。問題是，當我嘗試使用keras時，我不斷收到路徑錯誤。Keras已安裝但未能正常工作

$python 
>>import keras

給我的錯誤

我可以告訴大家，我需要添加到我的系統變量路徑（至少我是這麼認爲的......），但不管我加我仍然得到錯誤。我曾嘗試加入

C:\Python27\lib 
C:\Python27\lib\site-packages

基本上，它所說的任何路徑都不能指定。需要注意的是，我在安裝scipy時遇到了很多麻煩，必須從http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy獲取.whl文件才能確定是否有幫助。那是我的問題。

它可能找不到g ++，你有它安裝和在哪裏？ PATH中的路徑是什麼？ –

如果您沒有安裝g ++，請嘗試MinGW - 我在這裏找到了我的：https：//nuwen.net/mingw.html –

我也遇到了同樣的問題，並通過刪除其他python版本來解決。確保你只安裝了1個python。如果有多個，事情有時不能很好地工作。
