Hi,

May I know how do you install the TensorRT?
Please noted that you would need to use the OS and components from the same JetPack version due to the software dependencies.

Thanks.

Hi,

Could you check if the library exists in the below folder first:

/usr/lib/aarch64-linux-gnu/tegra/libnvdla_compiler.so

If yes, please try the below command before launching the application:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/aarch64-linux-gnu/tegra/

Thanks.
