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:
Hit ESC key to quit, 'a' to toggle animation, and 'e' to toggle cudaUnable to

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 project.Fabio. On Sunday, March 1, 2020, 04:29:05 PM MST, Fabio da

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:

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.

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)
