pyrsmi 0.2.0

pyrsmi
Python Bindings for System Management Library for AMD GPUs


pyrsmi is a python package of rocm-smi-lib, for providing a limited features of ROCm System Management Library for assisting Python development involving AMD GPUs.
It is based on (rocm-smi-lib)[https://github.com/RadeonOpenCompute/rocm_smi_lib], so its scope of support should be similar to that of the latter.

Requirements

pyrsmi runs on latest ROCm-supported Instinct MI-series GPU systems. Scope of tested systems is limited; please create tickets for any issues encountered.

How to install from source

Clone this repo:

git clone https://github.com/ROCm/pyrsmi
cd pyrsmi


python -m pip install -e .
pyrsmi can be installed as PyPA-compatible Python package.

How to install Python packages

Install build package:

pip install build


At the top directory (where setup.py is), run: python -m build
Then by default packages (both sdist and wheel) will be built under dist directory.
The packages can be either installed with pip install, or be uploaded to PyPI (release or test) repo, or an artifactory of your choice. The latter can be installed liked beflow.

How to install from PyPI

NOTE: Release versions are available at pypi.org, and the package can be installed with :

python -m pip install pyrsmi



How to use pyrsmi

Environment setup:

pyrsmi searches for rocm-smi library from default ROCm environment variable ROCM_PATH. So, for standard ROCm installation, the library will be automatically detected. In some unusual case where the ROCm installation is moved, make sure to set the environment variable as so :
$ mv /opt/rocm/ /usr/local/xyz/
$ export ROCM_PATH=/usr/local/xyz/




Running in python:
from pyrsmi import rocml

rocml.smi_initialize()
print(rocml.smi_get_device_count())
rocml.smi_shutdown()



Examples

Examples directory contains a number of code snippets showing how to use the package.
It also contains an example showing how to use pyrsmi to create a web-based system monitoring tool that displays various dashboards of system status, including memory, CPU/GPU utilization and process names.
