Hello,

I get the following error:

Code hier eingeben...Can not use cuDNN on context None: cannot compile with
cuDNN. We got this error:

Thanks for help.

You need to install cudnn. We don't install it for you.

Hi,

I have almost exactly the same error message, has it been resolved?

My understanding of installing cudnn is just to copy a few files into cuda
folder, correct?

Thanks!
