Cannot import Tensorflow for GPU on Windows 10

Question

Trying to install the gpu version of Tensorflow on my machine, but I'm getting this error when trying 'import tensorflow'

Running Windows 10, Python 3.5.2, Anaconda 4.2.0 64-bit. Installed tensorflow-gpu using 'pip install tensorflow-gpu'.

I've attempted the fixes in https://github.com/tensorflow/tensorflow/issues/5949, namely running Microsoft Visual C++ 2015 Redistributable Update 3 and confirming I had the following DLLs in System32/SysWOW64/my Python folder:

It's worth noting that the cpu version of Tensorflow imports and runs just fine, but when I attempt to use the gpu version I get the above error. I presume this is due to a mistake on my part in configuring the CUDA toolkit/cudNN, but I think I did everything listed in the instructions correctly. I made sure I had an entry in the PATH environment variable for the CUDA toolkit (leading to \bin and \libnvvp) and added one in for cudNN (leading to \cuda).

Any thoughts or other information you'd need to help?

Answer 1

Have you tried turning it off and on again? Seriously, though. If you have your command line terminal running during the CUDA and cuDNN installs, the environment variables aren't refreshed until you close and re-open the terminal. I know it's simple, but I struggled for an hour before a simple restart solved that same import error.

Answer 2

Try to rename cudnn64_6.dll to cudnn64_5.dll in C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0\bin.

Answer 3

You need to have CUDA_HOME leading to \cuda and %CUDA_HOME%\bin appended to your PATH. Also, tensorflow as of now only supports cudNN 5.1, please make sure you have that.
