TensorRT v4.0 was introduced with JetPack3.3, however, it also comes with CUDA 9 and cuDNN 7 but I am in need of TensorRT v4.0 for CUDA 8 compiled for ARM64, which is not available in JetPack.
Sorry that we don’t have a JetPack version including CUDA8.0 and TensorRT4.0 at the same time.
So you will need to change the software version based on JetPack release.
