Cannot loading Chinese language

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:

https://github.com/tleyden/docker/blob/master/open-ocr/Dockerfile#L45

[tleyden]

What happens if you remove the lang arg?

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

[an0]

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

[tleyden]

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

[lyhanyz]

using chi_sim replace chi-sim

[tleyden]

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

[xinerd]

tried chi_sim, solved problem. thanks
