How to deploy mxnet/ Tensorflow models with deepstream5?

I am totally new with the ML deploying,
I am using Ubuntu and installed deepstream5 and I ran the first 3 sample tests successfully, but i dnt know how to deploy my model that “takes the extracted features from pretrained mxnet model “slowfastNet” then using a simple tf classifier ( i could make that classifier mxnet as well)” but there’s no detailed tutorial about that, and is TensorRT another way to deploy than the Triton server ? and what should i use first ?
please i need a detailed answer, thank u
