Thank you for your kind request!
As mentioned above I wanted to run a chess program (lczero) on a jetson NX with cuda.
The Ubuntu 18.04 in the Jetson device comes with cuDNN-8 libraries and as pointed out by the author of the project [http://www.ezchess.org/ ] there is a bug in it preventing LCZero engine to load .
The work around proposed there is a downgrade to cuDNN-7.
This I did, I finally found two required files, and installed them as described in the project for the jetson NX .
libcudnn126.96.36.199 and cuda 10.2 seem to work for this project. However there are dependency errors which I cannot resolve and I cannot install further packages.
The avoid the dependency errors in other projects the jetson has to be booted from a second sdcard with cudnn8 installed. This of course is not really feasible, because it is a real pain in the neck to change the sd card (jetson in a metal case).
I wonder if cudnn188.8.131.52 can somehow coexist on the jetson NX with later versions i.e cudnn8… or if one can maybe switch between different cudnn versions.
Do you have any idea how to achive this???
Thank you so much for your care and help.
