numpy array problems.

Does anyone use rpyc with numpy arrays? I'm having some strange
behavior, but I'm just starting with rpyc, so I don't really know
where to start.
Here's an example:
Python 2.6.4 (r264:75706, Mar 5 2010, 22:31:14)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-46)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy
>>> import rpyc
>>> c = rpyc.classic.connect("localhost")
>>> a = numpy.array([1,2,3])
>>> type(a)
<type 'numpy.ndarray'>
>>> c.modules.numpy.max(a)
3
>>> c.modules.numpy.array([1,2,3])
array([1, 2, 3])
>>> c.modules.numpy.array(a)

I'm using rpyc 3.0.7, python 2.6.4, numpy 1.3.0.
I don't need to do this exact operation, but the operations I do want
to use (involving matplotlib) run into this exact same error.
Thanks,

I know this is a very old post, but do you have any solution to make numpy array work with rpyc? I encounter similar issue recently.
Thank you and best regards!
