Streamlit app does not update when theme is change in config.toml on repo

[hans]

Hello,

My folders in github are

root_repo/

• script.py
• .streamlit/config.toml

In my config.toml file I have only 2 lines
[theme]
base=“light”

The app runs on the streamlit cloud with link:
link to app

The application did not change to light. It used to be dark. The theme remains dark in the cloud.
Locally, I have the same folders and everything works fine if i run it. I see others have had unresolved issues on this. Any help is appreciated.

Python: 3.10
Streamlit: latest version
Conda: yes

Hi @hans,

Thanks for posting!

The link to your app is not working. Maybe the app is private? Did you deploy it from a private repo?

Send a public link so we can test it out. Share the code as well if you don’t mind for us to recreate it.

Sorry, changed to public. The repo however is private

From the docs:

If changes to .streamlit/config.toml are made while the app is running, the server needs to be restarted for changes to be reflected in the app.

Hello,

Thanks for taking the time to look at my issue. However, I have checked the docs and I have read this. So this is not the issue. It still remains on dark theme even after restarting the server. I have made our repo public for a while so you could have a look at our repo.

The link tho the app:
streamlit application

The link to to our repo
repo link

In our root repo named sysinv, the streamlit application is in the folder streamlit_template.
This folder contains the script named model_app.py and the config.toml file is in the .streamlit folder which is placed in streamlit_template folder also.

Really appreciate your help.

Regards
H

@hans

.streamlit/config.toml

must be in the root folder of the github repo, not relative to the streamlit app.

[hans]

Wow, so sorry. So easy to look over things when you are just starting out. You guys are awesome!. This solved it of course. Thanks!

PS: Let’s say we create 5 apps in one repo (our root repo on GitHub where all our projects are). So we can’t set themes separately for each app unless we make a root repo for each app with each of its own .streamlit folder and config.toml file?
Thanks again!
