Python utilities for the NVIDIA Management Library
Decision gist · record as of 2026-08-14
No. The package is explicitly deprecated and unmaintained as of version 13.0.1. The project's own documentation warns it is for demonstration only and recommends migrating directly to nvidia-ml-py. Unless you are maintaining legacy code that already depends on it, use nvidia-ml-py instead.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires NVIDIA GPU drivers and nvidia-ml-py (>=12.0.0) to be installed; NVML library must be accessible on the system.
- Low install friction with a single pure-Python dependency.
- However, the package is explicitly deprecated as of version 13.0.1 and marked as inactive; maintenance is not guaranteed.

What it is and what it does
pynvml is a deprecated Python utility wrapper around NVIDIA's Management Library (NVML) that lets you query GPU device information programmatically. It depends on the official nvidia-ml-py bindings and exposes utilities that mimic the command-line nvidia-smi tool, allowing you to retrieve GPU memory, utilization, and other hardware metrics. The package is no longer actively maintained and is marked for deprecation; the project explicitly recommends using nvidia-ml-py directly instead.
The main entry point provides a DeviceQuery method that accepts filter strings matching nvidia-smi's query API. It is intended for demonstration and monitoring tasks rather than production use, and there is no guarantee of long-term support or maintenance.
Use it for
- Monitor available GPU memory and total memory capacity on a system during development or testing.
- Query GPU device properties and utilization metrics in a Python script without shelling out to nvidia-smi.
- Prototype GPU monitoring or resource-tracking tools before committing to a maintained library.
- Retrieve structured GPU information for logging or diagnostic purposes in legacy codebases.
