Hello, I have an error

OSError: [Errno 24] inotify instance limit reached

I rebooted the app already several times

https://rcsmit-covidcases-covid-menu-streamlit-6cenk1.streamlitapp.com/

Here is a solution, but I can’t do it since I use the share.streamlit.io OSError: [Errno 24] inotify instance limit reached - #5 by tianyi_lIang

This is the log

Hi, are there any updates on this?

Facing the same issue when trying to deploy a Streamlit app with a custom component on Streamlit Cloud.

Tried following this thread. I would try to follow this response by setting a .streamlit/config.toml value, but apparently TOML doesn’t accept none, and alternatives like setting fileWatcherType = “none” in the [server] don’t work.

Hello!
In case you still need help, I simply installed inotify package through pip and added it to requirements.txt file. After that my app successfully deployed on streamlit cloud. I hope it would help you.

I had the same issue when deploying an app to streamlit cloud. I resolved it by creating a .streamlit/config.toml file in my project directory and adding the following lines to that file:

[server]
fileWatcherType = "poll"

According to the docs, “poll” means it will use polling to check for changes to files rather than the watchdog module, which is the module throwing the error. You could also try using “none” in place of “poll” if you don’t care about monitoring for changes to files, but I have not tried that.
