Hi all, I'm newbie. I got a lot of problem using xmlrpc and numpy
I'm using numpy to to some staff and then serve the results via a twisted/XMLRPC server. If the result is a numpy float 64, I get an exception cause probably twisted can't handle this type. Infact is I downgrade the result to float32 with x=float(x), everything is ok. This is not so good cause if I forget this workaroud somewhere, it's a pain. Have you any better solution?
server:
|from twisted.webimport xmlrpc, server
import numpyas np
class MioServer(xmlrpc.XMLRPC):
"""
An example object to be published.
"""
def xmlrpc_test_np(self):
return np.sqrt(2)
if __name__== '__main__':
from twisted.internetimport reactor
r= MioServer()
reactor.listenTCP(7080, server.Site(r))
reactor.run()|
client:
|import xmlrpclib
if __name__=='__main__':
x=xmlrpclib.ServerProxy('http://localhost:7080/')
print x.test_np()|
