About nvidia-nvtx

from the package's own PyPI description — quoted content, verbatim

A C-based API for annotating events, code ranges, and resources in your applications. Applications which integrate NVTX can use the Visual Profiler to capture and visualize these events and ranges.

AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

Provides a C-based API for annotating events and code ranges in applications to enable performance profiling and visualization with NVIDIA's Visual Profiler.

Medium install friction due to platform-specific wheels (manylinux1_x86_64, manylinux2014_aarch64, win_amd64); actively maintained with a release 79 days ago and no runtime dependencies to complicate setup.

License status is unclear—no SPDX identifier or raw license text is available in the package metadata, so users should verify licensing terms directly with NVIDIA before adoption.

Usage

pip install nvidia-nvtx==13.3.29
import nvidia_nvtx as nvtx
with nvtx.annotate('operation_name'):
    pass  # your code here

Requires Python >=3; platform-specific wheels mean installation may fail on unsupported architectures.

Verdict: A specialized profiling tool from NVIDIA in the top 1000 PyPI packages with active maintenance and no known vulnerabilities. Medium install friction and unclear licensing are the main considerations; otherwise suitable for CUDA-based ML and scientific workloads that need performance instrumentation.

Needs verification
