Installing cuDNN on Windows - No Performance difference

I followed the instructions on the deep Learning SDK documentation. I downloaded the drivers, installed the .dll, .h and .lib to the indicated directories. I checked that the environment variable is correct. I don’t know what’s needed for step 5, including cudnn.lib in the visual studio project. I’m using Python 6 and the pycharm IDE. CUDA is installed and working but I’m not getting any increase in speed since following the instructions to install cuDNN. How can I find out if it’s installed correctly? I haven’t gotten any error messages. Thanks, Doug
