In addition to the L4T-base container, CUDA runtime and TensorRT runtime containers are now released on NGC for JetPack 4.6.1.
NVIDIA SDK Manager Method
JetPack can also be installed or upgraded using a Debian package management tool on Jetson. We also host Debian packages for JetPack components for installing on host. Refer to the JetPack documentation for instructions.
Key Features in JetPack
NVIDIA L4T provides the bootloader, Linux kernel 4.9, necessary firmwares, NVIDIA drivers, sample filesystem based on Ubuntu 18.04, and more.
JetPack 4.6.1 includes L4T 32.7.1 with these highlights:
TensorRT is a high performance deep learning inference runtime for image classification, segmentation, and object detection neural networks. TensorRT is built on CUDA, NVIDIA’s parallel programming model, and enables you to optimize inference for all deep learning frameworks. It includes a deep learning inference optimizer and runtime that delivers low latency and high-throughput for deep learning inference applications.
JetPack 4.6.1 includes TensorRT 8.2.1
CUDA Deep Neural Network library provides high-performance primitives for deep learning frameworks. It provides highly tuned implementations for standard routines such as forward and backward convolution, pooling, normalization, and activation layers.
JetPack 4.6.1 includes cuDNN 8.2.1
CUDA Toolkit provides a comprehensive development environment for C and C++ developers building GPU-accelerated applications. The toolkit includes a compiler for NVIDIA GPUs, math libraries, and tools for debugging and optimizing the performance of your applications.
JetPack 4.6.1 includes CUDA 10.2
The Jetson Multimedia API package provides low level APIs for flexible application development.
Camera application API: libargus offers a low-level frame-synchronous API for camera applications, with per frame camera parameter control, multiple (including synchronized) camera support, and EGL stream outputs. RAW output CSI cameras needing ISP can be used with either libargus or GStreamer plugin. In either case, the V4L2 media-controller sensor driver API is used.
Sensor driver API: V4L2 API enables video decode, encode, format conversion and scaling functionality. V4L2 for encode opens up many features like bit rate control, quality presets, low latency encode, temporal tradeoff, motion vector maps, and more.
JetPack 4.6.1 includes following highlights in multimedia:
VPI (Vision Programing Interface) is a software library that provides Computer Vision / Image Processing algorithms implemented on PVA1 (Programmable Vision Accelerator), GPU and CPU
OpenCV is a leading open source library for computer vision, image processing and machine learning.
VisionWorks2 is a software development package for Computer Vision (CV) and image processing.
JetPack 4.6.1 includes VPI 1.2
JetPack 4.6.1 includes OpenCV 4.1.1
Jetpack 4.6.1 includes VisionWorks 1.61PVA is available only on Jetson AGX Xavier series and Jetson Xavier NX
2VisionWorks will no longer be included after JetPack 4.6.x. Developers should instead use the VPI library for computer vision and image processing. Refer to the announcement here.
CUDA Toolkit provides a comprehensive development environment for C and C++ developers building high-performance GPU-accelerated applications with CUDA libraries. The toolkit includes Nsight Eclipse Edition, debugging and profiling tools including Nsight Compute, and a toolchain for cross-compiling applications.
NVIDIA Nsight Systems is a low overhead system-wide profiling tool, providing the insights developers need to analyze and optimize software performance.
NVIDIA Nsight Graphics is a standalone application for debugging and profiling graphics applications.
JetPack 4.6.1 includes NVIDIA Nsight Systems 2021.5
JetPack 4.6.1 includes NVIDIA Nsight Graphics 2021.2
Refer to release notes for more details.
