Following these instructions, I have downloaded and installed Intel's OpenCL™ SDK (Intel® System Studio) from here. The cl.h file is in the folder
C:\Program Files (x86)\IntelSWTools\system_studio_2020\OpenCL\sdk\include\CL
however when running
pip install pyopencl
I get the long error message of
Building wheel for pyopencl (PEP 517) ... error
ERROR: Command errored out with exit status 1:

Mako is not installed.

That is not a problem, as most of PyOpenCL will be just fine
without it. Some higher-level parts of pyopencl (such as
pyopencl.reduction) will not function without the templating engine
Mako [1] being installed. If you would like this functionality to
work, you might want to install Mako after you finish
installing PyOpenCL.
Simply type
python -m pip install mako
either now or after the installation completes to fix this.

ERROR: Failed building wheel for pyopencl
Failed to build pyopencl
ERROR: Could not build wheels for pyopencl which use PEP 517 and cannot be installed directly
P.S.1. A semi-relevant issue also posted here.
P.S.2. According to this and this posts, there should be a siteconf.py file where I can specify the environment variables such as CL_INC_DIR and CL_LIB_DIR. However, I can't find the said file on my hard drive and I'm not sure if one can change the environment variables while using the pip package manager. I tried the
set CL_INC_DIR = [r'C:\Program Files (x86)\IntelSWTools\system_studio_2020\OpenCL\sdk\include']
in cmd with no avail.
P.S.3. I tried installing with pipwin:
pip install pipwin
pipwin install pyopencl
but when running import pyopencl in python I get the error message of
c:\python38\lib\site-packages\pyopencl\__init__.py in <module>
37
38 try:
---> 39 import pyopencl._cl as _cl
40 except ImportError:
41 import os
ImportError: DLL load failed while importing _cl: The specified procedure could not be found.
P.S.4. I tried following the instructions here, but the command
pip install -i https://pypi.anaconda.org/carlkl/simple mingwpy
returns
Looking in indexes: https://pypi.anaconda.org/carlkl/simple ERROR: Could not find a version that satisfies the requirement mingwpy (from versions: none) ERROR: No matching distribution found for mingwpy
回答1:
Few years back I experienced similar problem on Ubuntu and below helped me:
pip install --global-option=build_ext --global-option="-I/opt/AMDAPPSDK-3.0/include" --global-option="-L/opt/AMDAPPSDK-3.0/lib/x86_64" pyopencl
Of course the paths will need to be adjusted to your case. If it's still not working try to change paths to use forward slashes like on Unix/Linux - sometimes that is necessary despite being on Windows.
Alternatively you may want to use whl file which is already precompiled. For example here are some: https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyopencl
Then to install just do: python -m pip install <pyopencl_package.whl>

I went through this exact issue this morning. I was finally able to get it work by following the instructions here: http://www.minho-kim.com/courses/17sp43.635/pyopencl.html.
