Where are cudnn tar files located?

Hi guys, I’m currently using cuda10 and cuda9 at the same time.

It seems that NVIDIA cudnn legacy releases only provide .deb file for ubuntu16.04, which makes cudnn downgrade for cudnn7.4 cuda 10 to cudnn7.0 cuda9.

Thus, I need .tar file not to make cudnn downgraded.

Does anyone knows about this topic?

I see tar files here:

For example this is cuDNN 7.4.1 for CUDA 9:

this is 7.1.4 for CUDA 9:
