Map cannot be displayed in Jupyter lab but works fine in notebook

[frenet]

from arcgis.gis import GIS
gis = GIS()
gis.map()

Map cannot be displayed in Jupyter lab, but Map can be displayed in Jupyter notebook.
What's the reason, how to fix it?

When the .ipynb give errors "Error displaying widget: model not found",
Browser console log has following errors:
renderer.js:45 Error: widget model not found
at x.get_model (manager.js:341)
at p.renderModel (renderer.js:38)
