Driveworks9.0 failed to enable Object Detector Tracker functions

Dear Sir,
I enter the command to enable “sample_object_detector_tracker” sample functions, but it is terminated by “The engine plan file is generated on an incompatible device, expecting compute 7.2got compute 7.5, please rebuild”. I am not sure if there are any machine limitations for Drive AGX. Does it need any settings for the sample functions?

update the module name as below, it works…

volta-integrated

Dear melinda.hung,
It looks like you have DRIVE AGX Xavier platform which does not have discrete GPU.
The engine plan file is generated on an incompatible device, expecting compute 7.2got compute 7.5, please rebuild.

Compute capability 7.2 indicates Volta based GPU. So you should use tensorRT models generated for volta GPUs.
