looking in picca@sixs7:~/Debian/silx/silx/silx/opencl/test/test_addition.py
def setUp(self):
if ocl is None:
return
self.shape = 4096
self.data = numpy.random.random(self.shape).astype(numpy.float32)
self.d_array_img = pyopencl.array.to_device(self.queue, self.data)
self.d_array_5 = pyopencl.array.zeros_like(self.d_array_img) - 5
self.program = pyopencl.Program(self.ctx,
get_opencl_code("addition")).build()
I found that commenting this line
# self.d_array_5 = pyopencl.array.zeros_like(self.d_array_img) - 5
remove the pocl issue.
I remove everythings from the unit test.
@unittest.skipUnless(ocl, "pyopencl is missing")
def test_add(self):
self.assetTrue(True)
that means, only ther setUp and the tearDown are done.
with the line uncomment
(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

If now I do not import silx.io before there is no issue with or without the
commented line
(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

So what is going on when executing this line ???
self.d_array_5 = pyopencl.array.zeros_like(self.d_array_img) - 5
