Deployment error (on Streamlit Cloud)

Hi. My Streamlit app works perfectly fine when I run the code from VS Code (it redirects me to local host page where my app functions. However, everytime i try to deploy it, there’s always an error (for example an error of nltk, … and import generally) even though all the libraries are installed on my machine, and i made sure to include all the requirements in the requirements.txt file. Who can help me find out the problem please?

Unfortunately, this is far too little information to be able to help in any way.
