What is these identifier? compile error says that's undefined.

Hi.

Thanks for your code first. I can run cudnn/cuda deep learning example code successfully with yours.
By the way, I have question. When I make convolution using Makefile, the following error is occurred.
What can I do? What is the meaning of these identifiers?

maybe you can ignore the ERROR, and just ./train it

Hi,

Thanks for your reply first. By the way, It can't be ignored to compile and
run. Some syntax was changed in new(latest) cudnn version. So, I must
modify code as the updated library tutorial.

Sorry，I ignored the information about you can run the example code successfully. I thought you were struggling with the error information. Good luck

@KevinRyu
Yes, you need to modify the code to use ***_v7 for each related function calls. In src/layer.cu, it uses ***_v7 code. And, you may want to replace the algorithm options (like ***_PREFER_FASTEST) as 1.

Let me push updated version of convolution.cu in the near time.
