Hi, in some models we have layers like LSTM and scatter which are supported in tensorRT7.0 or tensorRT8.0 but not supported in tensorRT6.3.1.3.
If I need to add the unsupported layers as plugins into trenosrrt6.3.1.3? and where can I download the tensorRT6.3.1.3 code.
The tensorRT version will be update in later DRIVE OS?

Dear @wang_chen2,
When you install DRIVE OS using sdkmanager, tensorrt gets installed at /usr/src/tensorrt . The latest DRIVE release(DRIVE OS 5.2.6) has TRT 6.5. The future release are targeted for Orin based platform which will have TensorRT 8. Unsupported layers have to be integrated as plugin.

OK, I get it. Thank you very much.
