Installing an older version of cuDNN on Jetson Nano


I currently have CUDA 10.2 and cuDNN 8.0 installed on my Jetson Nano with Jetpack 4.4x, but I need to use cuDNN 7.x.

  1. Is there any way I can download cuDNN 7.x without installing an earlier Jetpack version? The cuDNN download archive appears to show that it is not possible.

  2. If I need to install an earlier Jetpack version, is there a way to do that without using a new SD Card or erasing what’s on the current SD card?


The package in the link is for the desktop user.
You will need to use the package from JetPack for the Jetson support.

To downgrade to the previous version, please also reflash your system for the GPU driver compatibility.
Since the os version is changed, the backup and cloning may not work.
This indicates you may not be able to preserve the data on the current system.

May I know which source do you want to use?
cuDNN v8.0 still holds some previous API for migration.
It’s more recommended to upgrade your source for cuDNN 8.0 instead.
