Closed pallashadow closed 7 years ago

pallashadow commented 7 years ago

I installed cntk via miniconda. I installed cudnn 6 manually some days ago, and planning to update it to cudnn 7. is there any way to check whether cudnn in correctly installed? and how can I print the cudnn version CNTK is currently using?

You can' use cuDNN 7 with CNTK, unless you build CNTK from the source. It need to link with cuDNN lib.

Each version of CNTK support only one cuDNN. There is no way to print which version of cuDNN CNTK uses.

CNTK expects cudnn 7.0, but there is no way to print this external/dynamic dependency. Follow https://docs.microsoft.com/en-us/cognitive-toolkit/setup-gpu-specific-packages-linux#cudnn for Linux and https://docs.microsoft.com/en-us/cognitive-toolkit/setup-gpu-specific-packages for Windows
