Hi @Grivine-19, welcome to the Streamlit community! 
I just read through spaCy’s documentation and it suggests adding the following to your requirements.txt:
spacy>=3.0.0,<4.0.0
https://github.com/explosion/spacy-models/releases/download/en_core_web_sm-3.0.0/en_core_web_sm-3.0.0.tar.gz#egg=en_core_web_sm
Try replacing spacy==3.0.6 in line 5 of your requirements.txt with the two lines above. Let me know if that works
