I think it would help a tiny bit if your post had a minimal amount of formatting. (I never trained online, however, so I don’t think I can help you.)
EDIT : I checked, and it might be that your content is formatted but the output is not. I cannot edit your post, so the editing is done by adding a \ at the end of a line so that the line return is displayed. A bit annoying, but at least it works.
Cheers
I have the similar problem, with the 0.13.0

hello, I have the same error, does anyone know how to fix it?
+1 here. Upgraded from 0.12.4 to 0.13.0 and immediately both training and running results in the above stack trace. Migration guide for this path doesn’t seem to mention any of relevance. Did anyone figure out how to fix this? Rasa?
Just to add more details to the above. This seems to be manifesting from the version of python - 3.5.2 which does not support or have a bug with types and annotations. As per this:
Could @Ghostvv or @akelad confirm that this the case?
I am running Ubuntu 16.04 and Python 3.5.2 is the highest standard package. It would be hlepful in the upgrade guide for Rasa to state that version 0.13 no longer works on 3.5.2 Currently it says that only python 2 support is dropped.
I installed python 3.6, but it’s non native, so no have to install rasa somehow into python 3.6 environment as I can’t remove python 3.5 from Ubuntu at risk of breaking it.
Suggestions? And could you confirm if 0.13.0 is truly not compatible with Ubuntu 16.04 and Python 3.5.2?
Thanks
yes, py3.5.2 has an issue with type annotations, there is a forum thread or GitHub issue somewhere
can you upgrade py3.5 to the latest version?
3.5.2 isn’t supported anymore: Add info that python >= 3.5.3 is required · Issue #3730 · RasaHQ/rasa · GitHub
Thank you @akelad and @Ghostvv. Since I’m running Ubuntu 16.04, I ended up installing virtualenv for python and actvating the virtual en with Python 3.6 in it and then installed Rasa 0.13.x into the virtual env and run it out of virtual env. Was a lot of work as i had to reinstall everything and retrain nlu and core for all the models, but socket.io started to work in that version. Woo hoo. But my slack channels buttons no longer do. 
lol. Suggestions? more upgrades to 0.14.x?
In general virtualenv seems to be a nice option for those not running it in the docker.
Yes, in general using a virtual environment is strongly recommended, it’s a lot less error prone. I’m not sure about the status of buttons in 0.13.x, Rasa 1.0 is the most stable version though
