The spacy-streamlit examples are intended to be run outside a notebook with

streamlit run ...

The concrete problem above is that displacy.render auto-detects that you're in a jupyter notebook and displays the output directly instead of returning HTML. However if you turn the auto-detection off, the result is no output because this code just isn't intended to be run within a notebook.

I don't know how stable it is, but you might try https://github.com/ddobrinskiy/streamlit-jupyter or look for similar libraries?
