Inference trt engine in python code

Hi all,
I trained FaceDetection/PeopleNet with TLT toolkit. I have some question:
1- Is it possible to convert the trained model to trt engine with TLT toolkit or need deepstream sdk for this step?
2- How to do inference with a trt engine on jetson nano in python code? Is there a sample code for this purpose?
