Re: [PyCUDA] installation pycuda2017.1.1 cuda9 debian9

[christoph]

Hello, thank you very much for your hint. It seems not to be related 
with my cuda 9 installation as the cuda samples compile well.


but anyway i have the impression that the hos compiler gcc6 makes a lot 
of trouble so I purged my cuda installation installed the debian 
cuda-toolkit packages(cuda 8)


and compiled a version of gcc4.9 as cuda 8 is incompatible to gcc6. now 
it seems to work!


will test it further.

cheers kris

This points to an issue with your CUDA installation. See if you can
compile and run a CUDA C example like the following:

https://www.quantstart.com/articles/Vector-Addition-Hello-World-Example-with-CUDA-on-Mac-OSX

using CUDA C. If you can, then PyCUDA should work for you. If you can't,
then something is wrong with your installation that is independent of PyCUDA.


and when I try to run the test script i get the following error although
pytest is installed.

Traceback (most recent call last):
File "test_driver.py", line 964, in 
  from py.test.cmdline import main
ImportError: No module named 'py.test.cmdline'; 'py.test' is not a package

This is known and will need to get fixed eventually. In the meantime,
use

python -m pytest test_driver.py

instead.
