Hi Alexander The server still had a stupid/broken assumption that the MultiModel phrase table would be first in the config. I updated the code that it is now specified by name by the client. This call should work for you (with the newest moses commit):
translate(['i have a dream'],server,[0.1,0.2], "PhraseDictionaryMultiModel0") On a related note: the phrase table format has recently changed (the constant phrase penalty was removed from the table and is now a separate feature function). This broke some assumptions in the MultiModel code, and it has now been fixed. This may lead to different results if someone wants to use the newest decoder, but has phrase tables with the phrase penalty (5 features instead of 4). To restore the original results, they need to modify their config file as follows: add PhrasePenalty to the [feature] section and modify the weight section as follows: before: [weight] PhraseDictionaryMultiModel0= 0.00402447059454402 0.0685647475075862 0.294089113124688 0.0328320356515851 -0.0426081987467227 after: [weight] PhrasePenalty0= -0.0426081987467227 PhraseDictionaryMultiModel0= 0.00402447059454402 0.0685647475075862 0.294089113124688 0.0328320356515851 0 best wishes, Rico On 27.12.2013 12:02, Калинин Александр wrote: > Hello, Rico > > I am using version 95a41c44facbfe49962b2b28234d0d0a08183032. > Previously there were not any messages, but after i rebooted the server it > started to respond with the following: > > ~/mosesdecoder/contrib/server$ sudo python ./client_multimodel.py > Traceback (most recent call last): > File "./client_multimodel.py", line 78, in <module> > translate(['i have a dream'],server,[0.1,0.9]) > File "./client_multimodel.py", line 27, in translate > print server.translate(params) > File "/usr/lib/python2.7/xmlrpclib.py", line 1224, in __call__ > return self.__send(self.__name, args) > File "/usr/lib/python2.7/xmlrpclib.py", line 1578, in __request > verbose=self.__verbose > File "/usr/lib/python2.7/xmlrpclib.py", line 1264, in request > return self.single_request(host, handler, request_body, verbose) > File "/usr/lib/python2.7/xmlrpclib.py", line 1297, in single_request > return self.parse_response(response) > File "/usr/lib/python2.7/xmlrpclib.py", line 1473, in parse_response > return u.close() > File "/usr/lib/python2.7/xmlrpclib.py", line 793, in close > raise Fault(**self._stack[0]) > xmlrpclib.Fault: <Fault -500: 'Unexpected error executing code for particular > method, detected by Xmlrpc-c method registry code.
