Windows中的Tensorflow-gpu安装错误

Question

最近我正在为Windows安装tensorflow（gpu）。 我有一个具有计算能力= 3.0（兼容）Python（3.5.2）Cuda 8.0（已安装且正在运行）的显卡（已按照tensorflow手册进行安装）但当我安装tensorflow时

pip3 install --upgrade tensorflow-gpu

已成功安装。 但是，当我在python中运行代码时，出现了错误。 这是日志。

任何人都可以找出问题所在。 我现在尝试在GPU上工作，但由于此错误而停留了数周

Answer 1

我非常努力地寻找解决此问题的方法。 我不知道您是否需要哪一个。 但最后我做到了，它奏效了：

您必须将目录C:\\Program Files\\NVIDIA GPU Computing Toolkit\\CUDA\\v8.0\\bin cudnn64_?.dll更改为cudnn64_5.dll 。

我希望它也对您有用。

更新实际上，您必须为您的张量CuDNN下载适当版本的CuDNN。 在Windows 10版本5.1中工作。

Answer 2

为深度学习/ ML库的GPU计算设置开发环境非常令人沮丧。 以我的经验，如果错误消息过于混乱，通常可以从空白处重新开始。 但是这个特定的错误消息似乎是在tensorflow的安装页面上提到的常见安装问题之一。 他们重定向到这个stackoverflow问题：

在Windows上，运行“ import tensorflow”不会生成名为“ _pywrap_tensorflow”的模块错误

从远处很难诊断出这种情况。 如果链接没有帮助，我希望其他人可以帮助您。 祝好运！
