Hi,
I set up NEMO as instructed. I was able to set up docker successfully.
I tried running the api/api_usage.ipynb notebook.
The "Run NER Model" section works as expected, but the rest of the models result in the following error:
JSONDecodeError: Expecting value: line 1 column 1 (char 0)

I'm guessing that yap isn't available. Can you look at the docker output and share the error you see there?

Do I need to set up YAP before I docker-compose up?
cjer commented
No, docker compose builds and starts both yap and nemo. There is a separate container for each. Is the yap container running? Can you share the full output of docker compose up?
SapirWeissbuch commented
I've just restarted it.

cjer commented
This is an out of memory error (137). Never had this happen for these containers. Docker is shutting down the yap container while it's trying to load its models. Maybe you have other containers running that you can free up? I advise you try to google it a bit for possible solutions.
cjer commented
What system are you running on? Operating system, CPUs, RAM?
SapirWeissbuch commented
I'm using a mac, 16 GB RAM. Anyway, I'm able to use NEMO's API without docker. (Just started NEMO and YAP with the instructions and it's okay).
cjer commented
Oh that should be more than enough. Good to hear you made it work for you. Closing this for now
