Hi
I see you try with triton server, then you need to use docker container, nvcr.io/nvidia/deepstream:5.0-dp-20.04-triton, which have tensorrt installed. and the tutorial is not for specific platform. the script is to download all the required open source models as well as converting the provided Caffe and UFF models to a TensorRT engine file.
Thanks amycao, it would be great if the original blog post could mention the above things, as that could save alot of time for absolute beginners like myself, who are new to the topic of Intelligent Video Analytics
