Good morning,
I was wondering if there are any binaries for OpenGL enabled PyCUDA for Windows 10. My
understanding (thanks, Andreas) is that it I will probably need to build it on my own.
Since I never did that, I went online and found some resources here
(https://stackoverflow.com/questions/19634073/pip-install-pycuda-on-windows) with the
source code from here
(https://files.pythonhosted.org/packages/5e/3f/5658c38579b41866ba21ee1b5020b…).
Specifically:1. Downloaded the source code from pythonhosted and untarred it.2. On the
main folder I ran:>> python configure.py3. Then I went to siteconf.py and enabled
OpenGL on line 9:CUDA_ENABLE_GL = True4. Finally I ran the commands:>> python
setup.py build>> python setup.py install
After that, I tried to open PyCUDA in an IPython window and got:ModuleNotFoudError: No
module named 'pycuda._driver'And obviously no pycuda.gl either.
I actually have a MSVC working and the CUDA toolkit successfully installed. I was running
PyCUDA successfully on miniconda till I ran the stackoverflow suggestion. Now PyCUDA is
broken and I can't recover from that yet. When I do recover, I would like to try
something else if possible and if any of you can help me, that would be great.
My application involves collecting some data from a digitizer, uploading and doing some
number crunching using a Titan V with PyCUDA and displaying the result through the OpenGL
interoperability capacity. So far, I have been pulling the result out of the Titan V,
building the image in the CPU and displaying it. For a 128x128 pixel image, I get
something like 5 Hz refresh rate and I hope to speed it up to 20 Hz or higher by using the
interoperability module. I am using Python 3.7.1 and VS 2017 version 15.9.8.
Thanks for any insights you may have.Cordially,Fabio.

If your build from above completed, then you should have PyCUDA
installed *somewhere*. This somewhere may just not be the same Python
interpreter as what your Jupyter notebook uses. You can find out where
these interpreters live by examining sys.path (from both the notebook
and the Python prompt for the Python that you used to build/install)
HTH,

Ok, I got it to work. Basically, the new build resides in a subfolder
named:build\lib.win-amd64-3.7
I then copied the pycuda folder and placed in my Miniconda lib
folder:Miniconda3\Lib\site-packages
I had to rename the current pycuda folder with pycuda.old to make sure I could revert.
When I do import pycuda.gl, it works. So I went ahead and downloaded the interoperability
example fromPyCuda/Examples/GlInterop - Andreas Klöckner's wiki
and ran it! There were some print usage that followed the Python 2.7 format that I
converted to Python 3.7 by putting the argument in parenthesis. I reran and the output
was:
Hit ESC key to quit, 'a' to toggle animation, and 'e' to toggle
cudaTraceback (most recent call last): File "pycuda-opengl-interop.py", line
292, in <module> main() File "pycuda-opengl-interop.py", line 249, in
main window = glutCreateWindow("PyCuda GL Interop Example") File
"C:\Users\fcss\Miniconda3\lib\site-packages\OpenGL\GLUT\special.py", line 73, in
glutCreateWindow return __glutCreateWindowWithExit(title,
_exitfunc)ctypes.ArgumentError: argument 1: <class 'TypeError'>: wrong type
I think this output may belong to another list (I haven't done my due diligence yet),
but if anyone knows about it and want to help, it will always be appreciated.
Cordially,Fabio.

Ok,
the error from the previous message is because, on line 249, the argument of
glutCreateWindow has to be b"PyCuda GL Interop Example" (notice the b before the
") instead of "PyCuda GL Interop Example". After that, there was an issue
related to the cl.exe and nvcc.exe compilers for MSVC and Nvidia not being in the system
path. Once all that was corrected, I was able to see the teapot spin around with not
response to the keys "a" and "e". I am assuming CUDA is working
because the speed of the output matches that of the MSVC interop .exe file. Still, in the
console where I ran the example, I got:

More due diligence, but I can now focus solely on the Python code.
Hope this helps others with the same issue.
Thanks, Andreas, again for the critical pointers to get me to move along with this
