So I have a problem, when my zoom is 5 and 8, some parts of map have wrong tile (the "base" of my custom tile).
My code:
f = folium.Figure(width=4680, height=4750)
m = folium.Map([36, 138], maxZoom=30, minZoom=4.8, zoom_control=True, zoom_start=5,
scrollWheelZoom=True,
tiles=my_tile,
attr='My tile',
maxBounds=[[25, 50], [120, 180]],
dragging=True).add_to(f)
Occasionally I was using 2 tiles styles, setting it by
folium.TileLayer('...').add_to(m)
and using tiles=my_tile
. So it caused this styling conflict. I just deleted the wrong one styling and everything worked fine.
