Question

我使用keras和theano作为后端在Windows 10上构建神经网络。我的python版本是2.7。问题是，当我尝试使用keras时，我不断收到路径错误。

$python
>>import keras

给我错误

我可以告诉我需要添加到我的系统变量路径（至少我是这么认为......）但是无论我添加什么，我仍然会得到错误。我试过添加

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

基本上它所说的任何路径都无法指定。需要注意的是，我在安装scipy时遇到了很多麻烦，不得不从http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy获取.whl文件，不确定是否有帮助。那是我的问题。

Answer 1

我也面临同样的问题，并解决了删除其他python版本。确保只安装了1个python。如果有多个，有时候事情就不会很好。

Answer 2

我建议在使用conda的单独环境中使用keras。
假设您要创建一个名为“ myenv”的环境
1.打开Anaconda promt并输入以下内容：

conda create --name myenv

2。要激活环境：

conda activate myenv

3。现在您可以安装keras和其他依赖项：

pip install keras

按如下所示安装tensorflow。

pip install tensorflow==2.0.0

已安装Keras但无法正常工作
