Error switching to new model

[mrob95]

Hi, just tried upgrading to the new (medium) model and I'm getting the following error message as soon as recognition begins. I'm on the latest versions and this grammar works fine on the zamia model. I've tried grepping a_I and it isn't coming from my files I don't think.

Traceback (most recent call last):

Let me know if you need any more details :) thanks

Edit: https://github.com/daanzu/kaldi-active-grammar/commit/892ab77b624ae9446d106fb60114d68d69220be9 maybe the fix for this? I tried to update to the latest but there is an assert statement in
the dragonfly engine code which fails on the dev version

Yeah, I think that should fix it, but I was afraid to post a point release without further testing, and I forgot that the backend would fail on a dev version. For the time being, you can safely delete lines 72-82 in /dragonfly/engines/backend_kaldi/engine.py. Let me know if it works!

Should be fixed now in 1.3.0 and the upcoming version of dragonfly.
