Using formula templates in MLN files produces errors. #5

Hello, I was trying to test HMM Alchemy example using mlnlearn and internal engine. It throws an error at 'processing line 'State(+s, 0)'. This seems odd, because '+' operator is supported, despite it is not in the proposed examples.

Probably there's something wrong with my test, as I am a newbie. Could you confirm me that '+' operator works?

Thanks These are the files I used https://alchemy.cs.washington.edu/mlns/tutorial/hmm/traffic.mln https://alchemy.cs.washington.edu/data/tutorial/traffic/traffic-train.db

My fault. I had to add weights (0) to the formula templates to make it learn. Of course it works now.
