Every time I call for RasaNLUInterpreter: nlu_interpreter = RasaNLUInterpreter('./models/nlu/default/weathernlu') I do not remember the steps that led to that problem, but I know it was after installing Flask.
It is an error with Spacy, a library for the advanced processing of natural language in Python and Cython and that serves as a backend to RasaNLU.
pip install rasa_nlu[spacy]
python -m spacy download en_core_web_md
python -m spacy link en_core_web_md en
And the error message is:

It seems that the problem was also found here but I do not understand the answer in English.
- Who asked the question proposes to use the "md" versions, which solved the problem, but it would be better if the "sm" versions would work too.
- Who created the library says that the problem is reduced to some symbolic links, and things overwrite in a way that we do not expect.
I really do not know what the first one meant, without knowing how to uninstall and without knowing who it was referring to, I reinstalled Spacy
