Hey @Victor_Umunna! Welcome back to our forum :slight_smile:

The usual print won’t work in Streamlit apps. Instead, you need to explicitly use Streamlit commands. Generally, you can swap print for st.write in all of the file here and that should do the job!

# Instead of...
print("something I want to see in my app")

# Use...
st.write("something I want to see in my app")

If you really want to stick with calling print, you can also check out the Capture extra here https://extras.streamlit.app/Capture

Hope that helps,

Best,
