Python bindings for NVIDIA CUDA APIs.

A Python interface to get GPU information, built with pybind11. The main purpose of this project is providing a solution for managing GPU information on OS X, because there is no NVML library on OS X.

You can use pynvx as:

• standalone API: pynvx.cuda*
• pyNVML wrapper: pynvml.nvml*, API call will be invoked to pyNVML on Linux and Windows, or pynvx on OS X.

• Prerequisites
• Installation
• APIs
• Special notes for Windows
• License
• Troubleshooting
• Test & Example
• Special Thanks

You should set up CUDA before installation.

Used When installing from source

On Unix (Linux, OS X)

• A compiler with C++11 support
• CMake >= 2.8.12

On Windows

• Visual Studio 2015, or Visual Studio 2017 for Python 3.11 and above (see notes below)
• CMake >= 3.1

pip install pynvx

Download wheel file in Release page, then install with pip:

pip install pynvx-*.whl

Please install CUDA and set environment variables first.

See FindCUDA.cmake:548 (message): Specify CUDA_TOOLKIT_ROOT_DIR in TROUBLESHOOTING.

Just clone this repository and pip install. Note the --recursive option which is needed for the pybind11 submodule:

git clone --recursive https://github.com/helloall1900/pynvx.git
pip install ./pynvx

With the setup.py file included in this project, the pip install command will invoke CMake and build the pybind11 module as specified in CMakeLists.txt.

• standalone API

  See API

• pyNVML wrapper

  Please install pyNVML when use pynvx as pyNVML wrapper:
  Python 3: pip install nvidia-ml-py3
  Python 2: pip install nvidia-ml-py

  See WRAPPER

Compiler requirements

Pybind11 requires a C++11 compliant compiler, i.e Visual Studio 2015 on Windows (Visual Studio 2017 for Python 3.11 and above). This applies to all Python versions, including 2.7. Unlike regular C extension modules, it's perfectly fine to compile a pybind11 module with a VS version newer than the target Python's VS version. See the FAQ for more details.

Runtime requirements

The Visual C++ 2015/2017 redistributable packages are a runtime requirement for this project. It can be found here. If you use the Anaconda Python distribution, you can add vs2015_runtime/vs2017_runtime as a platform-dependent runtime requirement for you package: see the conda.recipe/meta.yaml file in this example.

If you have problem while installing pynvx, see TROUBLESHOOTING before opening an issue.
