Hi @infinityp913, the TensorRT packages can be installed via apt repo or from SDK Manager. These aren’t on the website because TensorRT version is dependent on the cuDNN/CUDA version, which is in turn dependent on the JetPack-L4T version, ect (which is why these are bundled with JetPack).
SDK Manager will download the deb packages to your host PC for you, and you can install those yourself. TensorRT does require cuDNN and CUDA Toolkit to be installed also.
