Hello fanzh,
I referred the link that you provided but i am not getting idea how to change things.
There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one. Thanks
the TensorRT version does not support RoiAlign Ops. and Jetson nano DeepStream can’t be upgraded to a higher version. please refer to Quickstart Guide — DeepStream 6.3 Release documentation. please ask the repo author if have the same issue on Jetson Nano+DS6.0.1.
