Error on poly_table when initalizing with grabcut.result (gv.Path)

[kcpevey]

I'm trying to use the grabcut.result to feed into a new annotator for additional editing and attributing. Instantiating the annotator doesn't throw an error, but if I try to visualize poly_table I'm getting an error.

ann = PolyAndPointAnnotator(path_type=gv.Path,  
                            tile_url='https://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer/tile/{Z}/{Y}/{X}',
                            crs=proj_param.get_crs(), points=[],
                            polys=grabcuts.result, poly_columns=['type'])
(ann.tiles * ann.polys * ann.points + ann.poly_table).cols(1)

@jlstevens @philippjfr - Any ideas on what's going on here?

[kcpevey]

This is happening even when I explicitly reinstantiate the dframe as a gv.Path.

gvpath = gv.Path([grabcuts.result.dframe()], kdims=['Longitude', 'Latitude'], crs=ccrs.PlateCarree())
ann = PolyAndPointAnnotator(path_type=gv.Path, extent=(np.NaN,)*4, 
                        tile_url='https://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer/tile/{Z}/{Y}/{X}',
                            crs=proj_param.get_crs(), points=[],
                            polys=gvpath, poly_columns=['type'])

I'm thinking this might be a bug.

[kcpevey]

@philippjfr Can you weigh in on this?

[philippjfr]

Looking at this tonight.

[philippjfr]

Once again I can't reproduce this, although I can't fully reproduce your example since I do not know what proj_param.get_crs() is, so what I tried was:

ann = PolyAndPointAnnotator(path_type=gv.Path,  
                            tile_url='https://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer/tile/{Z}/{Y}/{X}',
                            crs=dashboard.result.crs, points=[],
                            polys=dashboard.result, poly_columns=['type'])
(ann.tiles * ann.polys * ann.points + ann.poly_table).cols(1)

For reference here are my versions:

GeoViews: '1.5.4a8.post2+g400b850' HoloViews: ''1.11.0a5.post12'

[kcpevey]

Looks great. I had the same hv but my gv was very slightly behind yours. Everything works now!
