hi
i am tryig to use the community streamlit to build an app to change a pdf.
for this i would need the streamlit app to use the pypdf2 library.
I’m so sorry if this is a dumbe question, but streamlit is so great for beginners!!!

Hi @Frank_Yates
Welcome to the community!
You can have Community Cloud install any libraries as you would with pip install by specifying the name of the libraries in requirements.txt file:
PyPDF2
WoW thanks a lot.
Do I need to « reboot » the streamlit app every time I add a new library to the txt file?
I am going to try this and confirm here, for all beginners and noobs how it goes. So sorry for the questions which must seem easy for all of you.
Yes @Frank_Yates. You need to reboot application whenever you add new library. Feel free to ask.
Happy Streamlit-ing

It works great now, thanks for your answers.
To summarize: if you need external libraries, make sure they
are listed in a file called requirements.txt in the root of your github folder, and that you
click on …>reboot app
Yes @Frank_Yates
