I installed tensorflow 1.0.1 GPU version on my Macbook Pro with GeForce GT 750M. Also installed CUDA 8.0.71 and cuDNN 5.1. I am running a tf code that works fine with non C
This is cudnn compatible issue. Check what you installed that is using the GPU for instance, tensorflow-gpu. What is the version? Is the version compatible with the version of your cudnn and is the cudnn installed the right version for your cuda?.
I have observed that:
cuDNN v7.0.3 for Cuda 7.*
cuDNN v7.1.2 for Cuda 9.0
cuDNN v7.3.1 for Cuda 9.1 and so on.
So also check the correct version of TensorFlow for your cuda configurations.
For instance -using tensorflow-gpu:
TF v1.4 for cudnn 7.0.*
TF v1.7 and above for cudnn 9.0.*, etc.
So all you need to do is to reinstall the appropriate cudnn version. Hope it helps!
