rasa_core.server:Can not access action 'None'?

antoinecomp · February 8, 2019, 3:53pm

I’m using:

rasa-core==0.12.0
rasa-nlu==0.13.7

When running train_online.py, I have an error after saying hi to the chatbot « ERROR:rasa_core.server:Can not access action 'None', as that name is not a registered action for this domain. Available actions are: … »:

The default ‘Loader’ for ‘load(stream)’ without further arguments can be unsafe.

Use ‘load(stream, Loader=ruamel.yaml.Loader)’ explicitly if that is OK.

Alternatively include the following in your code:

import warnings

warnings.simplefilter(‘ignore’, ruamel.yaml.error.UnsafeLoaderWarning)

In most other cases you should consider using ‘safe_load(stream)’

data = yaml.load(stream)

I don’t have any None actions. Is it linked to the fact that I have day: None, duration: None, hour_start: None, name_room: None after asking hi ?

Do you have any ideas ?
