PyOpenCL lets you access GPUs and other massively parallel compute
devices from Python. It tries to offer computing goodness in the
spirit of its sister project
Object cleanup tied to lifetime of objects. This idiom, often called
RAII <https://en.wikipedia.org/wiki/Resource_Acquisition_Is_Initialization>_ in C++, makes it much easier to write correct, leak- and crash-free code.
Completeness. PyOpenCL puts the full power of OpenCL's API at your disposal, if you wish. Every obscure
get_info()query and all CL calls are accessible.
Automatic Error Checking. All CL errors are automatically translated into Python exceptions.
Speed. PyOpenCL's base layer is written in C++, so all the niceties above are virtually free.
Helpful and complete
Documentation <https://documen.tician.de/pyopencl>__ as well as a
Liberal license. PyOpenCL is open-source under the
MIT license <https://en.wikipedia.org/wiki/MIT_License>_ and free for commercial, academic, and private use.
Broad support. PyOpenCL was tested and works with Apple's, AMD's, and Nvidia's CL implementations.
install instructions <https://documen.tician.de/pyopencl/misc.html#installation>_

What you'll need if you do not want to use the convenient instructions above and instead build from source:
- gcc/g++ new enough to be compatible with pybind11
numpy <https://numpy.org>_, and
- an OpenCL implementation. (See this
howto <https://wiki.tiker.net/OpenCLHowTo>_ for how to get one.)
