Hi all,
I'm observing the following behavior with latest (git-fetched today)
pycuda and opencl versions on Snow Leopard 10.6.4:
$ python
>> import pycuda.driver
>> import pyopencl
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File
"/Library/Python/2.6/site-packages/pyopencl-0.92beta-py2.6-macosx-10.6-i386.egg/pyopencl/__init__.py",
line 3, in <module>
import pyopencl._cl as _cl
AttributeError: 'NoneType' object has no attribute '__dict__'
$ python
>> import pyopencl
>> import pycuda.driver
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File
"/Library/Python/2.6/site-packages/pycuda-0.94rc-py2.6-macosx-10.6-i386.egg/pycuda/driver.py",
line 1, in <module>
from _driver import *
AttributeError: 'NoneType' object has no attribute '__dict__'
This worked with stable versions. Does anyone know why is this happening?
(One may ask why do I need both libraries in the same program. I have
the set of tests for my module, which can use both Cuda and OpenCL,
and it is convenient to run all the tests using the single file.
Although it is not a critical issue, I'm just curious).
Best regards,
Bogdan

Are you using the shipped version of Boost in both libraries? If so,
that might present an issue.

Yep, in both. Does it behave in the same way on your system?

HTH,

You were right, I built both libraries against boost 1.44.0, and it
helped. Thanks!
(I hoped that it would also fix the bug with 64-bit pycuda build, but,
unfortunately, it didn't)
Best regards,
Bogdan

Because Debian packages do not use shipped Boost
(I build them with Debian Boost libraries)
this problem does not exist.
I have not, however, checked whether running
CUDA and OpenCL programs at the same time work.
Regards.

Hello,
I'm getting the same error here.
Andreas -- any pointer to where this could come from? Let me know what
you think and I'll start working on a patch.
Thanks.
Regards,
Nicolas
