Problem rendering with leafmap.Map() + lonboard about leafmap HOT 12 CLOSED

v0.31.4 has been released. Try pip install -U leafmap. The conda-forge package might be available in a few hours.

from leafmap.

The recent lonboard updates might caused this. I will look into it.

I already identified the root cause of the issue. Will be fixing it later today.

I believe the issue has been resolved in #693. Will be releasing a new version shortly.

It is an upstream issue. See developmentseed/lonboard#365

from leafmap.

I don't get the error but it doesn't render anything. I saw the upstream issue, but they are saying it's because it's using a private method and they close it, so not sure what's going on.

I'll do a clean install and check again.

This is what I get when I run the same code now.

from leafmap.

For the record

m = leafmap.Map()
m

renders the world map, but as soon as I try to do m.add_vector(...) the rendering turns out empty

from leafmap.

In fact, if I try to run the similar examples from your notebooks here https://leafmap.org/notebooks/83_vector_viz/ in colab, after installing lonboard.

If you add the rendering of m in any of the cells that add something like :

streets = gpd.read_file("nyc_streets.shp")
m.add_gdf(streets, zoom_to_layer=True, pickable=True, get_width=5)
m

or

m.add_vector("nyc_subway_stations.shp", get_radius=10, get_fill_color=[255, 0, 0, 180])
m

You will see that it doesn't render.

Just for the record: I tried downgrading to lonboard==0.5.0 but didn't work either :/

Thank you @giswqs 🙌
