最近我正在为 windows 安装 tensorflow(gpu)。我有一张计算能力 = 3.0（兼容）Python（3.5.2）Cuda 8.0（已安装并正常工作）CudNN 的显卡（这些是根据 tensorflow 手册）但是当我安装了 tensorflow

pip3 install --upgrade tensorflow-gpu

它已成功安装。但是当我在 python 中运行代码时，我得到了错误。这是日志。

我非常努力地寻找解决这个问题的方法。我不知道哪一个对你来说是必要的或不需要的。但最后我做到了，它奏效了：

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

我希望它也对你有用。

更新事实上，你必须CuDNN为你的 tensorflow 下载足够的版本。在 Windows 10 5.1 版中有效。

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，如果错误消息变得过于复杂，通常可以重新从空白开始。但是这个特定的错误信息似乎是 tensorflow 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”会生成 No module named “_pywrap_tensorflow”错误

从远处很难诊断出这样的事情。如果链接没有帮助，我希望其他人可以来帮助你。祝你好运！
