JetPack 4.3 Release

Deep Learning

JetPack 4.3 – L4T R32.3.1 is now available!

There are a whole bunch of great new features. Two that are particularly noteworthy:

And if you are getting ready to use the upcoming Jetson Xavier NX or its big brother Jetson AGX Xaver, there’s a developer preview of Vision Programming Interface (VPI). VPI is a software library that provides Computer Vision and Image Processing algorithms implemented on Xavier Vision Accelerator, GPU and CPU. 

JetPack 4.3

Here is the official blurb from the NVIDIA Jetson forums:

We are pleased to announce JetPack 4.3 supporting Jetson AGX Xavier series, Jetson TX2 series, Jetson TX1, and Jetson Nano.

JetPack 4.3 key features include new versions of TensorRT and cuDNN, Docker support for CSI cameras, Xavier DLA, and Video Encoder from within containers, and a new Debian package server put in place to host all NVIDIA JetPack-L4T components for installation and future JetPack OTA updates.

Please refer to the JetPack Release Notes and L4T Release Notes for additional info.

JetPack 4.3 Highlights:

  • Support for TensorRT 6.0.1 and cuDNN 7.6.3
  • Full support for DLA INT8 on Jetson AGX Xavier
  • Support for installation of JetPack components via Debian package archives
    • JetPack components are provided as Debian packages via a public APT server hosted by NVIDIA, enabling easier upgrades of JetPack components to future versions. Previous versions of JetPack need to be re-flashed to JetPack 4.3, after which the APT server can be used.
  • Support for CSI, DLA, and Video Encoder from within containers
    • On all Jetson products: Camera Serial Interface (CSI) and NVENC are now supported from within containers.
    • On Jetson AGX Xavier series only: NVIDIA Deep Learning Accelerator (DLA) engines are now supported from within containers.
  • Support for DeepStream 4.0.2
  • Support for ISAAC SDK version 2019.3
  • New easy to use tool to configure 40-pin header on Jetson developer kits
  • Developer preview of VPI (Vision Programing Interface), a software library that provides Computer Vision and Image Processing algorithms implemented on Xavier Vision Accelerator, GPU and CPU. 
    • GPU and CPU implementations are not optimized for performance in this preview release of VPI. A future release will bring performance optimized GPU and CPU implementations
