Run this script only once, on any node in your cluster. Notes ----- The dispatcher expects to find worker scripts already running. Make sure you run as many workers as you like on your machines **before** launching the dispatcher. How to use distributed :class:`~gensim.models.ldamodel.LdaModel` ---------------------------------------------------------------- #. Install needed dependencies (Pyro4) :: pip install gensim[distributed] #. Setup serialization (on each machine) :: export PYRO_SERIALIZERS_ACCEPTED=pickle export PYRO_SERIALIZER=pickle #. Run nameserver :: python -m Pyro4.naming -n 0.0.0.0 & #. Run workers (on each machine) :: python -m gensim.models.lda_worker & #. Run dispatcher :: python -m gensim.models.lda_dispatcher & #. Run :class:`~gensim.models.ldamodel.LdaModel` in distributed mode : .. sourcecode:: pycon >>> from gensim.test.utils import common_corpus, common_dictionary >>> from gensim.models import LdaModel >>> >>> model = LdaModel(common_corpus, id2word=common_dictionary, distributed=True) Command line arguments ---------------------- .. program-output:: python -m gensim.models.lda_dispatcher --help :ellipsis: 0, -7 N)Queue)utils)LDA_WORKER_PREFIXzgensim.models.lda_dispatcher i3zgensim.lda_dispatchercjeZdZdZedfdZejdZejdZ ejdZ ejdZ ejdZ ejd Z ejejejd d Zd Zejd ZdS) DispatcherzDispatcher object that communicates and coordinates individual workers.

Log this event and then asynchronously transfer control back to the worker. Callback used by workers to notify when their job is done.
