hello, while preparing the package, I get this error

If I try to execute from pyFAI.opencl import ocl, I get this error message

picca@mordor:~/Debian/pyfai/pyfai$ PYTHONPATH=/home/picca/Debian/pyfai/pyfai/.pybuild/cpython2_2.7_pyfai/build python2.7

Here the sys.path

>>> import sys
>>> sys.path
['', '/home/picca/Debian/pyfai/pyfai/.pybuild/cpython2_2.7_pyfai/build', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-i386-linux-gnu', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages/PILcompat', '/usr/lib/python2.7/dist-packages/gtk-2.0', '/usr/lib/python2.7/dist-packages/wx-3.0-gtk3']

we can see that '' is the first path

If I change the current dir, it works.

picca@mordor:~/Debian/pyfai$ PYTHONPATH=/home/picca/Debian/pyfai/pyfai/.pybuild/cpython2_2.7_pyfai/build python2.7
Python 2.7.15+ (default, Aug 31 2018, 11:56:52) 
[GCC 8.2.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from pyFAI.opencl import ocl

and the sys.path is identical to the precedent.

picca commented 5 years ago

I instrumented the code of /home/picca/Debian/pyfai/pyfai/.pybuild/cpython2_2.7_pyfai/build/pyFAI/azimuthalIntegrator.py in order to print the sys.path

and I get this

['/home/picca/Debian/pyfai/pyfai/.pybuild/cpython2_2.7_pyfai/build', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-i386-linux-gnu', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages/PILcompat', '/usr/lib/python2.7/dist-packages/gtk-2.0', '/usr/lib/python2.7/dist-packages/wx-3.0-gtk3']

now we do not have ''

picca commented 5 years ago

Ok, this is a bad interaction with the --no-opencl option. If I remove --no-opencl from the command line it works.
