Hello, I am trying to use xml-rpc to be able to run some simulations remotely. I am running into a problem with the transfer of numpy arrays. my server code looks like: #!/usr/bin/env python def again(x): # test out the sending of data return [x,x] from SimpleXMLRPCServer import SimpleXMLRPCServer SimpleXMLRPCServer.allow_reuse_address = 1 server = SimpleXMLRPCServer(("", 8000)) server.register_function(again) try: print "Serving..." server.serve_forever() # Start the server finally: print "done." server.server_close() my client code looks like: import numpy from xmlrpclib import ServerProxy server=ServerProxy('http://localhost:8000') server.again(5) # this works b=numpy.random.rand(5,5) server.again(b) # this gives an error this gives the error: : cannot marshal objects which seems to be a deficiency of the marshal library, or perhaps I am doing something wrong. Is there a way to fix this? Is there another approach that I should be using? thanks, Brian Blais -- Brian Blais bblais@bryant.edu http://web.bryant.edu/~bblais
