Problem with Blei-Lafferty scoring

[karmake2]

Hi Chase and Sean,

I am doing Topic Modeling with python 3.7 using meta.

The following command hangs and does not output anything:

model.top_k(topic, 10, metapy.topics.BLTermScorer(model))

However,
model.top_k(topic, 10) works fine.

Can you check?
