Funny you mention those. I've been really excited about Edward but when I tried it for a project last year I could never get it to come together in the right way. I got the sense that it wasn't quite ready for prime time yet, although very promising. My memory of it was that a lot of claimed flexibility in how to specify models wasn't really implemented fully. The experience also turned me off of TensorFlow a bit. But that was a year ago, so maybe it's improved? I ended up doing it in Stan in part because I was more familiar with that, and it worked out fairly well. Just a personal anecdote.
