Hi Andreas
I found that the pycuda .whl was a combination install for pycuda 2017.1.1 + 
Cuda 8.0.6.1 for win64 and python 3.6.

I suspect that while the install was successful my test programs are failing 
because I have Cuda 9.0.

I am home now for the Sabbath but on Sunday I will see if I can install a 
compatible who + cuda version.

I am sorry that I did not see this earlier. 

Best, Arnold

I am not sure PyCUDA likes being built with Mingw; I'd recommend the
MS compiler (or Christoph Gohlke's binaries) on Windows. At the very
least, you'd have to adjust the CXXFLAGS config variable to not include
flags that only the MS compiler will recognize. Alternatively, PyOpenCL
does much the same thing as PyCUDA and is included in conda forge.

Re: [PyCUDA] test program hello_gpu.py and simplespeedtest.py

2017-10-27 Thread Arnold Tunick 
 Hi Andreas,    Thank you for your email. While PyOpenCL may be useful, in the 
long run my CNN has Pycuda as a software dependency and so I would like to keep 
trying.   Previously, I downloaded a .whl file directly from 
http://www.lfd.uci.edu/~gohlke/pythonlibs/#pycuda and used pip install. I tried 
that again today and it appeared to be successful.
 
(C:\ProgramData\Miniconda3) C:\Users\atunick\Documents>pip install 
pycuda-2017.1.1+cuda8061-cp36-cp36m-win_amd64.whl
Processing 
c:\users\atunick\documents\pycuda-2017.1.1+cuda8061-cp36-cp36m-win_amd64.whl
Installing collected packages: pycuda
Successfully installed pycuda-2017.1.1+cuda8061
However, when I try to run hello_gpu.py or simplespeedtest.py I get the error 
message that I reported earlier, i.e.,   File 
"C:\ProgramData\Miniconda3\lib\site-packages\pycuda\driver.py", line 5, in 

    from pycuda._driver import *  # noqa
ImportError: DLL load failed: The specified module could not be found.
.Don't I need to run a setup.py file or something similar for this .whl install 
to build pycuda?
Yet there is not a setup.py file in the newly created folder 
C:\ProgramData\Miniconda3\Lib\site-packages\pycuda.
Please adviseThank you.Arnold
