What it is

jetson-inference is a TensorRT-accelerated deep learning inference library for NVIDIA Jetson embedded GPUs, enabling C++ and Python deployment of optimized neural networks for vision tasks like image classification (imageNet), object detection (detectNet), semantic segmentation (segNet), pose estimation (poseNet), and action recognition (actionNet). It bridges PyTorch training on development machines with real-time inference on edge devices through TensorRT graph optimization and Jetson-specific CUDA kernels. C++-first monorepo: c/ contains core inference engines (imageNet.cpp, detectNet.cpp, etc.) with CUDA kernels (.cu files), c/plugins/ implements custom TensorRT layers (FlattenConcat,…

Start here

Open these first:

• c/tensorNet.h — Core base class for all DNN inference networks; all vision primitives inherit from this, making it the foundational…
• c/tensorNet.cpp — TensorRT engine initialization, model loading, and inference execution logic; the primary entry point for GPU-accelerated…
• c/detectNet.h — Object detection network interface and core API; one of the five primary vision primitives and a reference implementation…
• c/imageNet.h — Image classification network interface; demonstrates the standard pattern for wrapping TensorRT models and is frequently…
• CMakeLists.txt — Build configuration for the entire project; defines dependencies, targets, and compilation flags for C++/CUDA code and…

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Clone and build from source: git clone https://github.com/dusty-nv/jetson-inference.git && cd jetson-inference && mkdir build && cd build && cmake .. && make -j$(nproc). Or use the Docker container: `docker build -t j…

Daily commands:

After build: ./detectNet --network=ssd-mobilenet-v2 --input_blob=input_0 --output-cvg=scores --output-bbox=boxes /path/to/image.jpg (C++ CLI), or python3 detectNet.py --network=ssd-mobilenet-v2 /path/to/image.jpg (P…

Key cautions & unknowns

• Slowing — last commit 7mo ago
• Single-maintainer risk — top contributor 90% of recent commits
• CUDA Compute Capability coupling: code compiled for one Jetson arch (e.g., Orin with sm_87) may not run on another (Xavier with sm_72)—rebuild required. TensorRT engine serialization: .trt files are version-specific and…
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.

Evidence note

Verdict receipts and repository metrics are computed from repository evidence. Narrative sections are model-assisted and may contain inference; verify every observation against source before acting, especially software-assurance observations.
