Hello again,
I am very sorry that I keep you busy with this issue.
1. Error message : The same as the one with the double precision arithmetic
even if it was np.float32. Then I thought that perhaps there is no
compatibility between ctype float and numpy float. I got a similar message
with the np.int64 in the same routine as pyvienna did not accept either
np.int64 or np.int32. I resorted to python and casted all my integer
variables with int(). pyvienna accepted python int.
2. the print gave a "*None*" error message
I just wanted to be sure that my devices are compatible with opencl and I
downloaded pyOpenCL today. I run a simple test and pyOpenCL detected all of
my devices.
I have AMD's latest OpenCL SDK. I installed it about a month ago.
I just wonder if you could provide - for everybody - a simple python code
that checks and verifies the installation. It may include the name of
device(s), platform compatibility, etc. If this test succeeds, then the
issue lies in pyvienna.
In order to install the pyOpenCL, I downloaded pyvienna at the moment. Now,
I am sure that I have a compatible system.
I thank you very much for your efforts again.
Have a nice weekend.
Kind regards,
Berat
