我正在尝试按照以下说明安装 tensorflow 和 tensorflow-gpu：
https://www.tensorflow.org/install/install_windows#CommonInstallationProblems
我想我正确地遵循了它们，但我似乎无法让它发挥作用。如果我以管理员身份从 CMD 提示符运行它，两者似乎都安装成功。如果我在安装 tensorflow 后停止，它会起作用。但是，一旦我也安装了 tensorflow-gpu（即使它似乎安装成功），当我尝试使用 tensorflow 时，就会出现错误。
这是我得到的错误：

我正在通过以管理员身份运行并激活运行的 CMD 提示符进行此安装。我也在 PyCharm 中尝试过类似的结果。
说明说即使我打算使用 tensorflow-gpu，我也应该安装常规的 tensorflow。
但是我尝试只安装 tensorflow-gpu，虽然安装说成功，但在运行“import tensorflow as tf”时仍然出现上述错误。
所以我似乎可以让它工作的唯一方法是如果我不安装 tensorflow-gpu。但是，我这样做的全部原因是我可以将我的 NVIDIA GPU 与 Keras/Tensorflow 结合使用。
注意：我确实安装了 CUDA Toolkit 8.0 和 cuDNN v5.1，虽然这个过程很混乱，所以我可能做错了什么。我认为没有简单的方法来验证它。
为了踢球，我尝试先安装 tensorflow-gpu，然后在仅安装 tensorflow 时出现以下错误——尽管是管理员，但出现权限错误：

这个问题是一个类似的问题： Tensorflow GPU installation Error Windows 10 Anaconda
但是，我确实确保我的路径指向正确的位置。
