With that in mind, [pymc3 seems appealing](http://pymc-devs.github.io/pymc3/getting_started/#probabilistic-programming-in-python-using-pymc) for specifying large discrete latent variable models. You can't write them as a Stan program, and it could be rather annoying to code them up in raw TensorFlow or NumPy/SciPy.\r\n\r\nOn the other hand, it's one more modeling language to maintain; pymc3 actually uses Theano as a backend, which may lead to some bugs(?); and I don't know how popular pymc3 would be as a use case over the other supported languages."},"comment":{"url":"https://api.github.com/repos/blei-lab/edward/issues/comments/217972704","html_url":"https://github.com/blei-lab/edward/issues/20#issuecomment-217972704","issue_url":"https://api.github.com/repos/blei-lab/edward/issues/20","id":217972704,"user":{"login":"twiecki","id":674200,"avatar_url":"https://avatars.githubusercontent.com/u/674200?v=3","gravatar_id":"","url":"https://api.github.com/users/twiecki","html_url":"https://github.com/twiecki","followers_url":"https://api.github.com/users/twiecki/followers","following_url":"https://api.github.com/users/twiecki/following{/other_user}","gists_url":"https://api.github.com/users/twiecki/gists{/gist_id}","starred_url":"https://api.github.com/users/twiecki/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/twiecki/subscriptions","organizations_url":"https://api.github.com/users/twiecki/orgs","repos_url":"https://api.github.com/users/twiecki/repos","events_url":"https://api.github.com/users/twiecki/events{/privacy}","received_events_url":"https://api.github.com/users/twiecki/received_events","type":"User","site_admin":false},"created_at":"2016-05-09T20:02:14Z","updated_at":"2016-05-09T20:02:14Z","body":"Regarding the autodiff -- is there an API for the model gradient?"}}
