Hello Streamlit Community!
I am hosting a streamlit app on Heroku, and have noticed an issue when more than one user is attempting to render Matplotlib figures (specifically seaborn cluster map). Two things tend to happen - either the app immediately crashes and all users are disconnected until the app refreshes to the original title page, or the error below is shown to one user while the other is able to continue rendering the image. Any advice/solutions to this issue? Has anyone else experienced this?
