Please find my first Nvidia Jetson Nano project at
arvcode/TensorRT_classifier_efficientNet: Real Time TensorRT based object classification using EfficientNet CNN (github.com)
and the blog post that contains details of the project at
TensorRT based Real Time Object Classification using EfficientNet on Nvidia Jetson Nano. | by Arvindh Srinivasan | Apr, 2021 | Medium
It also has a list of Jupyter notebooks that contain steps starting from loading a pre-trained model until inferencing using TensorRT.
I hope this can be useful for anyone who would like to quickly understand the flow of deploying a model with TensorRT.
