Device-SMI 0.4.0

Retrieve gpu, cpu, and npu device info and properties from Linux/MacOS with zero package dependency.

Device-SMI

Self-contained Python lib with zero-dependencies that give you a unified device properties for gpu, cpu, and npu. No more calling separate tools such as nvidia-smi or /proc/cpuinfo and parsing it yourself.

News

• 02/26/2025 0.4.0 Added AMD GPU support. Validated with amd-smi on 7900XTX. Use PowerShell for auto-device selection on Windows platform.
• 12/20/2024 0.3.3 Patch fix for Windows install compatibility.
• 12/05/2024 0.3.2 Added Windows WSL support.
• 12/03/2024 0.3.1 Added CPUDevice compat for Windows.
• 12/02/2024 0.3.0 Added OSDevice.[name, version, kernel, arch] for Linux/MacOS/Windows/FreeBSD/Solaris. Added cpu.[count, cores, threads] properties. Bug fix for gpu device index.
• 11/29/2024 0.2.1 Added pcie.[gen, speed, id] + [firmware, driver] properties to GPU device.

Features

• Retrieve information for both CPU and GPU devices.
• Includes details about memory usage, utilization, driver, pcie info when applicable, and other device specifications.
• Zero pypi dependency.
• Linux/MacOS support

Supported Devices:

• OS: Linux, MacOS, Windows, FreeBSD, Solaris
• CPU: [Intel/AMD/Apple] Linux/MacOS system interface
• NVIDIA GPU: NVIDIA System Management Interface nvidia-smi
• Intel XPU: Intel/XPU System Management Interface xpu-smi
• AMD ROCm/GPU: AMD System Management Interface amd-smi
• Apple GPU: MacOS interfaces

Usage

For OS, use os to init a new Device object.

from device_smi import Device

dev = Device("os")
print(dev)

Output: (Ubuntu 22.04)

{'type': 'os', 'name': 'ubuntu', 'version': '22.04', 'kernel': '6.12.1-x64v3-xanmod2', 'arch': 'x86_64'}

For GPU/XPU, use [gpu, cuda] for Nvidia and xpu for Intel/XPU. Index usage for multiple GPUs: cuda:0

from device_smi import Device

dev = Device("cuda:0")
print(dev)

Output: (Nvidia 4090)

{'pcie': {'gen': 2, 'speed': 1, 'id': '00000000:16:00.0'}, 'gpu': {'driver': '565.57.01', 'firmware': '95.02.3C.40.E7'}, 'type': 'gpu', 'model': 'geforce rtx 4090', 'memory_total': 25757220864, 'vendor': 'nvidia', 'features': ['8.9']}

For CPU, use cpu to init a new Device object.

from device_smi import Device

dev = Device("cpu")
print(dev)

Output: (AMD EPYC 7443)
