To install pyopencl on a Windows system:

  1. Find out what Python version you are using.
  2. Go to this site: https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyopencl and download the whl file for your python version. E.g., I tested this install method using a Python 3.7.9 (64bit) environment, so I downloaded the file pyopencl‑2020.3.1+cl12‑cp37‑cp37m‑win_amd64.whl (PyOpenCL version 2020.3.1, OpenCL version 1.2, Python version 3.7, 64bit). Note that there are two OpenCL versions, 1.2 and 2.1 (i.e., cl12 and cl21). Start by trying to install the cl12 version first, and if that fails, uninstall pyopencl and then install the cl21 version.
  3. Install the whl file using: pip install <wheel_file_name>, e.g., pip install pyopencl‑2020.3.1+cl12‑cp37‑cp37m‑win_amd64.whl
  4. Test the installation by starting python, then doing:
import pyopencl as cl
print(cl.get_platforms())
  1. You should see something like: [<pyopencl.Platform 'AMD' at 0x11234567890>]
  2. If you need to, to uninstall pyopencl from your Python environment, do pip uninstall pyopencl
