(1) Jetson Nano development: Download and install JetPack (many details)

Write first

1. This article aims to install JetPack 4.2 version , relying on developer.nvidia.com official website to create a lot of details.
2. If it is to adapt to Tensorflow, people who come here suggest not to download and install the higher version of JetPack on the official website. The higher the version, the better , but compatibility should be considered!
