Error using starter-pack-rasa-stack

Getting Started with Rasa

Hey I installed all the libraries but running this seems to throw an error with Python 3 vs 2. Any suggestions?

(env) BL-C02TP2MHHTD8:starter-pack-rasa-stack danielw$ make cmdline
python -m rasa_core.run -d models/current/dialogue -u models/current/nlu --endpoints endpoints.yml

Hey just checking in if anyone’s seen this. I’ve tried installing 3.6.4 of Python and updating my rasa packages to the latest version.

This only happens when I run the make cmdline command.

I think you train the model with python 2, and now use python 3 to use model and run the bot. This may cause some encoding problems.
