The final result of the '05_load_raster' example is not showing in Google Colab

Hi, exploring the leafmap package examples using Google Colab I had a problem with the 05_load_raster example. After adding the rasters via Map.add_raster() the Map class can't be displayed.

# ! pip install xarray_leaflet leafmap 

import os
import leafmap.leafmap as leafmap

out_dir = os.path.expanduser('~/Downloads')

if not os.path.exists(out_dir):
    os.makedirs(out_dir)

landsat = os.path.join(out_dir, 'landsat.tif')
dem = os.path.join(out_dir, 'dem.tif')

if not os.path.exists(landsat):
    landsat_url = 'https://drive.google.com/file/d/1EV38RjNxdwEozjc9m0FcO3LFgAoAX1Uw/view?usp=sharing'
    leafmap.download_from_gdrive(landsat_url, 'landsat.tif', out_dir, unzip=False, verbose=False)

if not os.path.exists(dem):
    dem_url = 'https://drive.google.com/file/d/1vRkAWQYsLWCi6vcTMk8vLxoXMFbdMFn8/view?usp=sharing'
    leafmap.download_from_gdrive(dem_url, 'dem.tif', out_dir, unzip=False, verbose=False)

Map = leafmap.Map()

Map.add_raster(dem, colormap='terrain', layer_name='DEM')
Map.add_raster(landsat, bands=[5, 4, 3], layer_name='Landsat')

# Map class is not displayed
Map

The add_raster function relies on xarray-leaflet, which only supports ipyleaflet. Colab don't not yet support ipyleaflet yet. You will need Jupyter to run this example. Also, xarray-leaflet does not support Windows. See https://github.com/davidbrochart/xarray_leaflet/issues/30

Thank you for the answer. Was this issue fixed (in particularly ipyleaflet support by colab)?

I have added a binder icon to each notebook. You can run the notebook examples using the link below.
