st_folium keeps reloading Streamlit page till page crashes

Streamlit page keeps reloading every 3 seconds till it crashes. Now I use st_static that is not recommended ?

st_data = st_folium(m, key='map',width = 650, height = 600)

Any idea what is happening ?

@PaulShin83 I don’t see that issue when I fun the following script with streamlit==1.11.0 and streamlit-folium==0.6.13

import streamlit as st
from streamlit_folium import st_folium
import folium

def draw_folium_map():
    center = [39.5, -98.5]
    tiles = ["cartodbpositron", "Stamen Toner", "OpenStreetMap"]
    map = folium.Map(
        location=[center[0], center[1]],
        zoom_start=10,
        zoom_control=True,
        scrollWheelZoom=False,
        tiles=tiles[0],
    )

    folium.Marker(
        location=[39.5, -98.5],
        popup=f"A location!",
        icon=folium.Icon(color="blue", icon="star"),
    ).add_to(map)

    return map


m = draw_folium_map()

output = st_folium(m, key="map", width=650, height=600)

st.write(output)

I know this isn’t exactly the same as your script, but I’m unable to run your exact example without the full script. It’s possible that the issue you’re encountering is related to something happening with session state (e.g. perhaps rendering the map -> updates session state -> rerendering the map -> …). Would you be able to share the full script, or a complete subset of it that shows the infinite-reload issue?

@tonkolviktor Thanks for sharing that example code! In this case, it seems to be behaving as expected – I don’t see it reloading over and over again. The “running guy” does trigger, but that is because the map is returning different values. If you want to avoid this, you can pass returned_objects=[] to st_folium, to make it return nothing (and essentially behave like folium_static. But, you can also still have it return some data if you want it to. If you want to avoid the “running guy”, the returned_objects=[] will always be available. I may even keep folium_static and simply make it call st_folium with that argument passed in. But, if there are cases where st_folium produces an infinite-rerun, I definitely want to fix those before changing folium_static to work that way.
