Hi Community,

I am trying to run the default object_detector_sample provided with driveworks 5.6 but am running into the below given error.

It seems the model provided with the sample was serialized with some old version of tensorrt optimization tool.

I would like to know the model name and architecture so that I can convert it using the latest tensorrt optimization tool and test it,

My own custom model is working fine as I converted it using new optimization tool.

Thanks.

Dear @priyam1,
This topic looks related to DRIVE AGX ORIN platform. If so, please post at DRIVE AGX Orin - NVIDIA Developer Forums .
There are some issues with DW 5.6 samples and we recommend to wait until next release.
May I know if this issue block your development?

Hi @SivaRamaKrishnaNV , I had tagged this issue as part of AGX Orin but one of the moderators changed it to AGX Xaviers and AGX General.

Anyways, I appreciate your help. I cannot go into detail but yes, this issue is blocking our development as we need a reference/baseline for our model performance as well as a better understanding of the entire DNN pipeline in Driveworks. We plan on getting that using the default model.

Dear @priyam1,
Please reinstall the DRIVE OS 6.0.4 + DW 5.6 and test.
