[PyOpenCL] no attribute 'get_sub_region'

[Dustin Arendt]

Hi,

I am trying to create & pass a sub region of an OpenCL buffer to my kernel, but it is not working.  It seems, that even though get_sub_region is document as a method of the Buffer class, this is not present in my version of pyopencl.  The error I am receiving is:

AttributeError: <class 'pyopencl._cl.Buffer'> has no attribute 'get_sub_region'

and, indeed, there doesn't appear to be any method with that name in the version I am using:

In [27]: pyopencl.Buffer.
pyopencl.Buffer.__abstractmethods__  pyopencl.Buffer.__module__

pyopencl.Buffer.__le__               pyopencl.Buffer.release

I am using pyopencl version 2011.1.2 on OSX Snow Leopard.  Am I somehow doing something wrong, or is this method for some reason not available?

Thanks,
