What if I want to specify Duckling’s URL at runtime? For example, if I’m developing a piece of code, and I have the same deployed somewhere, I would like to switch between dev environment (http://localhost:8080) to prod (http://my-url:/12345) using a flag, and not always changing it manually.

Is it possible?

Never-mind, I’ve found in the source code that it’s just:

os.environ["RASA_DUCKLING_HTTP_URL"] = "http://localhost:9000"

Hi, I want my bot to schedule meetings. When the user says- “schedule a meeting after 2 hours”, it should understand this and reply something like- “sure, I have scheduled a meeting at 5:30 PM” Where 5:30 PM is relative time after two hours from the current time.

Can I use duckling for such cases? If yes, can you help me with some code snippets? Thanks in advance.
