I’m baffled and hoping for some help. I’ve got a streamlit app to detect vacant parking spaces in short video clips from a live youTube stream. It’s running locally no problem, so I’ve deployed it to streamlit sharing.
Here’s my gitHub repo for reference: Parking_vacancy
When I run the option in my app “Live data” the first time, it works great. This downloads trained weights and runs detect with Mask R-CNN on frames from the video.
When I re-run the app and process live data again, it crashes halfway through the image detection process. Not at the beginning, but somewhere in the middle (200ish of 500ish frames).
I suspect this somehow has to do with either caching or running our of system resources, but don’t know enough to figure it out.
Here’s the log from the manager. You can see the app was rebooted (top lines), then run once. Then again (repeated warnings from tensor flow). Then it crashes with no apparent error besides
