安装Tensorflow-GPU

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

我认为我正确地关注它们，但我似乎无法让它发挥作用。如果我从CMD提示符作为Admin运行它，两者似乎都成功安装。如果我在安装tensorflow之后停止，它就可以了。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时我得到一个错误。

这是我得到的错误：

我正在通过以管理员身份运行的CMD提示执行此安装，并启用了运行。我也在PyCharm中尝试过类似的结果。

说明书说我应该安装常规张量流，即使我打算使用tensorflow-gpu。

但是我尝试只安装tensorflow-gpu，虽然安装说它成功了，但在运行“import tensorflow as tf”时仍然会出现上述错误。

所以我似乎唯一能让它工作的方法就是我不安装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一起使用。

注意：我确实安装了CUDA Toolkit 8.0和cuDNN v5.1，虽然这个过程很乱，所以我可能做错了。我认为没有简单的方法来验证它。

对于踢，我尝试先安装tensorflow-gpu，然后在安装tensorflow时出现以下错误 - 尽管是管理员的权限错误：

这个问题是一个类似的问题： Tensorflow GPU installation Error Windows 10 Anaconda

但是，我确实确定了我的路径指向了正确的位置。

1 个答案:

答案 0 :(得分：0)

嗯，我修好了，但说实话，我不太确定我尝试过哪些事情。

我再次仔细检查了这些步骤。这仍然没有用，虽然它可能已经解决了一些前兆问题。然后我进入Path Environment Variable并开始添加新路径，以便Tensorflow更容易在我的Conda环境中为Keras / Tensorflow查找内容。特别是，我查找文件“pywrap_tensorflow”（它找不到的文件）并找到它并添加了一个特定的路径。我不知道这是否必要。但最后，它工作，我现在可以运行tensorflow gpu。
