I have a function that collects comments from youtube livestreams and the function can take up to 1 hour until it’s finished. I noticed that my app stops running after a longer time. So I was wondering if streamlit has like a maximum length of minutes that a function can run. If not I have to look …

In the case of 20-40 min long-running processes, I would consider how you can split your code into the Streamlit front-end and a processing backend. For example, you could move the actual monte carlo simulation to something like FastAPI, so that Streamlit requests a run and then you periodically ch…

Hi @MaxMnemo - I think it’s important to step back and think about the bigger picture…websites generally don’t have a pattern where you wait for an hour for something to happen. So yes, Streamlit does functionally have a timeout (probably 10-15 minutes before the websocket is closed, not sure exact…

Yeah, i should reconsider how I gather the data. I work with the pytchat module that helps you collecting livestream comments without selenium and beautifulsoup and it needs a longer connection to gather the data. After around 15 mins the running animation in the top right corner stops. That fits w…

@randyzwitch @marduk , I’m also curious to know the answer. I’m using Streamlit to empower users to run Monte Carlo simulations which take 20-40 mins. Sometimes the processing completes, but the results aren’t displayed. Other times the page just refreshes while the processing continues in the backe…

Unfortunately I have no solution for that. Maybe try a cloud solution. Compute the simulation within google cloud and await the results.

Hi, thanks for these answers. I’m having a similar issue. I have Streamlit calling my backend function, according to the settings input by each user. Every few minutes it logs something to the Streamlit interface. And then periodically the Streamlit front end resets. What I don’t understand is: If …

I’m facing that same challenge right now. It’s difficult to “check if the run is complete” without a logged-in user (and Streamlit doesn’t support user authentication very well). One solution could be to generate a unique identifier for the job, show it to the user, and store the results in a data…

I do something similar to the unique identifier. I ask the user for a string that I use as a prefix for his tables that I’ll create. Every step in the job writes a temporary table, using that prefix. Also, when he starts his job, I add a record to a history table with his prefix and other settings. …

Hi @enegy , Did you find a solution for this? I have a similar use case to you, where I want to run some Monte Carlo simulations for engineering that can run from 30 mins to 48 hours. In this case, the code would run overnight and the user can see the results later. Is this possible on streamlit? I…
