[rpyc] Metaclass >> How to access methods of ?

[baco]

Hi all,
I have a <netref class 'numpy.ndarray'> object (server side) and I can't 
access to any of method (in particular the .tostring()). 
Data from this object is ok, but need to have the 'real' numpy.ndarray from 
my client, to use it.
thanks for help
