What happened?

Installed with pip install rasa[full]==3.0.0rc2 and tried training moodbot. Training fails with the end message being:

In rasa==2.8.x, we used to detect this upfront and throw this error:

Steps to reproduce: From rasa home directory make install-full This gets the spacy library, which is needed, but not the spacy model (the condition you want to be in)

Once rasa is installed, go to the examples/moodbot folder of rasa and run rasa train. The error should then appear.

Alternatively, you can remove the spacy model with the following:

• assuming that you already have the spacy model downloaded in your python virtual environment, you can delete it with pip by running pip uninstall <model-name> . So, if the model name wasen-core-web-md (the one that is used by examples/moodbot ) then you can run pip uninstall en-core-web-md.

To again download the model, you can run python -m spacy download en_core_web_md
