Key error: sklearn.preprocessing

Community Cloud

Hello @randyzwitch

I met the same error message. However, the error message is “from sklearn import preprocessing”.
I don’t think this belongs to cloud secrets management functionality and I go through the docs, don’t find a solution.
Any suggestion or solution on this? Thank you so much!

Hi @Tony1, welcome to the Streamlit community!

Do you have all of your requirements in a file in your repo, so that Streamlit Cloud can install the dependencies you need?

Best,
