As per the topic title, is it possible to only update my existing TensorRT4.0 to TensorRT5.xx? I have flashed Jetson TX2 with jetpack 3.3 couple of months ago.
I wanted to try out introductory example of tensorRT provided in https://devblogs.nvidia.com/speed-up-inference-tensorrt/
But I get error since nvonxxparser.h with tensorRT4.0 does not contain class IParser. A quick check on another device with TensorRT5.0 confirms availability of the class in the header file.
I am afraid of extra efforts towards flashing Tx2 with jetpack4.2 and setup of various toolchains.
Thanks in advance!
