Tensorflow-gpu 1.9 不适用于 Pycharm

Question

I can't import tensorflow in pycharm, it raises the following error:

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

I checked this cudart file and its added in %PATH%

It is working on CLI and python shell perfectly.

I have

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

echo %PATH%

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

Looking into the tensorflow-1.9 release branch , it looks like they used CUDA 9.0 and CUDNN 7.1.4

So I think you should download CUDNN 7.1.4. Hopefully, the issue will be fixed.

You can check everything works by running this handy script written by one of the authors of the tensorflow . It will show you exactly what is not working right.

EDIT: For CUDA 10.0 it's CUDNN version 7.6.2.24-1 (see here ).
