Where is TensorRT on Jetson Nano

I have just fired up Jetson Nano 4G ready to experiment with AI solutions and I cannot find how to start with TensorRT Looking through installation descriptions while other sources say it is already installed, I see that python is at 2.7 so it all does not make much sense to me.
How do I start ?

I think what you are looking for can be found here.

Hi @szarotka33, TensorRT should already be installed under /usr/src/tensorrt

If you are interested, this tutorial uses TensorRT to run the inferencing: https://github.com/dusty-nv/jetson-inference
