Try passing: "engine_args": {"lang": "chi-sim"} to the REST API. You should see this:

Hmm, I checked the dockerfile and it has chi-sim:

tleyden commented 8 years ago

What happens if you remove the lang arg?

"engine_args": {} does it work in that case?

an0 commented 8 years ago

Yes, it works for “eng”. I checked that too. Did you try "chi-sim" yourself to see whether it works for you?

tleyden commented 8 years ago

Nope, I haven't actually tried chi-sim yet

lyhanyz commented 8 years ago

using chi_sim replace chi-sim

tleyden commented 8 years ago

@an0 can you try chi_sim? Re-open the ticket if that doesn't fix it.
