Getting cuDNN Version [Linux]

Use following to find path for cuDNN:

cat $(whereis cudnn.h) | grep CUDNN_MAJOR -A 2

If above doesn't work try this:

cat $(whereis cuda)/include/cudnn.h | grep CUDNN_MAJOR -A 2

Getting cuDNN Version [Windows]

Use following to find path for cuDNN:

C:\>where cudnn*
C:\Program Files\cuDNN6\cuda\bin\cudnn64_6.dll

Then use this to dump version from header file,

type "%PROGRAMFILES%\cuDNN6\cuda\include\cudnn.h" | findstr "CUDNN_MAJOR CUDNN_MINOR CUDNN_PATCHLEVEL"

Getting CUDA Version

This works on Linux as well as Windows:

nvcc --version
