I decided to concentrate myself on one opencl test (addition) So I deactivated all other test by commenting the test in silx/opencl/__init__.py
If I do not import silxs.io, this test works (sid_amd64-dchroot)picca@barriere:~$ PYOPENCL_COMPILER_OUTPUT=1 PYTHONPATH=silx-0.11.0+dfsg/.pybuild/cpython3_3.7_silx/build python3 test.py -v .Maximum valid workgroup size 2048 on device <pyopencl.Device 'pthread-Intel(R) Xeon(R) CPU E5-2640 v2 @ 2.00GHz' on 'Portable Computing Language' at 0x12b5d30> ---------------------------------------------------------------------- Ran 1 test in 0.030s OK If I add silxs.io, it fails (sid_amd64-dchroot)picca@barriere:~$ PYOPENCL_COMPILER_OUTPUT=1 PYTHONPATH=silx-0.11.0+dfsg/.pybuild/cpython3_3.7_silx/build python3 test.py -v pocl error: lt_dlopen("(null)") or lt_dlsym() failed with 'can't close resident module'. note: missing symbols in the kernel binary might be reported as 'file not found' errors. Aborted so this test is ok in order to investigate this issue. -- debian-science-maintainers mailing list debian-science-maintainers@alioth-lists.debian.net https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/debian-science-maintainers
