Tensorflow-gpu 1.9没有在Pycharm上工作

Question

我无法在py魅力中导入tensorflow，它会引发以下错误：

ImportError: Could not find 'cudart64_90.dll'. TensorFlow requires that this DLL be installed in a directory that is named in your %PATH% environment variable. Download and install CUDA 9.0 from this URL: https://developer.nvidia.com/cuda-toolkit

我检查了这个cudart文件并添加了%PATH%

它正在完美地处理CLI和python。

我有过

CUDA v9.0
cuDNN v7.0.5
tensorflow-gpu v1.9

回波%路径%

C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.0\bin;
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.0\libnvvp;
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.0\extras\CUPTI\libx64;

Answer 1

查看tensorflow-1.9 释放枝，看起来他们使用了CUDA 9.0和CUDNN 7.1.4

所以我认为你应该下载CUDNN 7.1.4。希望这个问题能得到解决。

您可以通过运行这个由脚本的作者之一编写的方便的tensorflow来检查一切工作。它会让你确切地知道什么是不正确的。

编辑:对于CUDA 10.0，它是CUDNN版本7.6.2.24-1 (见这里)。
