I’m trying to follow the ML annotator example from pyviz dot org.
I’m running jupyterlab from the pangeo-notebook docker image which includes:
- holoviews = 1.14.0
- jupyterlab = 2.2.9
- labextension: @pyviz/jupyterlab_pyviz v1.0.4
Here is the code from the example:
import holoviews as hv
import geoviews as gv
hv.extension('bokeh')
tiles = gv.tile_sources.EsriImagery()
tiles
pts = dict(
Longitude = [-121.932619100, -121.932362392, -121.933530027],
Latitude = [ 36.631164244, 36.629475356, 36.630623206])
opts = dict(size=10, line_color='black', padding=0.1, min_height=400)
points = gv.Points(pts).opts(**opts)
points_annotator = hv.annotate.instance()
hv.annotate.compose(tiles, points_annotator(points, annotations=dict(Size=int, Type=str)))
When I run it in jupyterlab, nothing is displayed.
I can display the points and tiles in an overlay: points * tiles. This works as expected based on the example.
But the annotator creates empty output in the notebook. Rather than displaying the expected result from the example.
I hope some one can point me in the right direction. Thanks!
