[Bug][Jupyter Widget] Error displaying widget: model not found (still)

Description I have been struggling with the problem described in this issue and this one for a few days now. I’ve tried the instructions but they don’t seem to fix the problem. I can’t reopen the issue so I have created a new one here.

To Reproduce When I type:

from keplergl import KeplerGl
map_1 = KeplerGl()
map_1

I get:

User Guide: https://docs.kepler.gl/docs/keplergl-jupyter
Error displaying widget: model not found

Developer console error:

manager.js:319 Uncaught (in promise) Error: Module keplergl-jupyter, semver range ^0.2.0 is not registered as a widget module
    at WidgetManager.loadClass (manager.js:319)
    at WidgetManager.<anonymous> (manager-base.js:264)
    at step (manager-base.js:45)

    at WidgetManager.<anonymous> (manager-base.js:247)
    at step (manager-base.js:45)

Expected behavior I expect to see a slippy map.

Environment (please complete the following information):

• Python 3.6.8
• Windows 10 jupyter --version

jupyter core     : 4.6.3
jupyter-notebook : 6.0.3
qtconsole        : 4.7.5
ipython          : 7.15.0
ipykernel        : 5.3.0
jupyter client   : 6.1.3
jupyter lab      : 2.1.4
nbconvert        : 5.6.1
ipywidgets       : 7.5.1
nbformat         : 5.0.6
traitlets        : 4.3.3

jupyter labextension list

JupyterLab v2.1.4
Known labextensions:
   app dir: C:\Users\[USER]\.conda\envs\py36\share\jupyter\lab
        @jupyter-widgets/jupyterlab-manager v2.0.0 enabled  ok
        @jupyterlab/toc v3.0.0 enabled  ok
        js v0.1.0 enabled  ok
        jupyter-gmaps v0.9.0 enabled  ok
        jupyter-leaflet v0.13.0 enabled  ok
        jupyterlab-jupytext v1.2.1 enabled  ok
        jupyterlab-stata-highlight v0.1.1 enabled  ok
        keplergl-jupyter v0.2.0 enabled  ok

Additional context The problem seems to affect any extensions with a slippy map, including gmaps and ipyleaflet. I believe it arose when I downloaded and started to use kepler (probably from updating some packages in the process?) since gmaps used to work. To be clear, it’s fine in Jupyter notebook, just not in lab.

Any thoughts would be much appreciated!

The best workaround I found so far is to wrap it in an iframe like this:

import keplergl
import base64

map1      = keplergl.KeplerGl()
orig_html = str(map1._repr_html_(),'utf-8')
b64d_html = base64.b64encode(orig_html.encode('utf-8')).decode('utf-8')
framed_html = f'<iframe src="data:text/html;base64,{b64d_html}" style="width:95%; height: 600px">'
import IPython
IPython.display.HTML(framed_html)

I also got the same bug report with jupyter lab, but jupyter notebook works.

• python error

Error displaying widget: model not found

• console error

renderer.js:45 Error: widget model not found at C.get_model (manager.js:375) at h.renderModel (renderer.js:38) renderModel @ renderer.js:45

• macOS version: 10.15.6
• node version: v12.18.3
• keplergl vesion: 0.2.0

Here are my jupyter version:

jupyter core : 4.6.3 jupyter-notebook : 6.1.1 qtconsole : 4.7.5 ipython : 7.16.1 ipykernel : 5.3.4 jupyter client : 6.1.6 jupyter lab : 2.1.5 nbconvert : 5.6.1 ipywidgets : 7.5.1 nbformat : 5.0.7 traitlets : 4.3.3

All jupyter lab extensions are installed and enabled:

JupyterLab v2.1.5 Known labextensions: app dir: /opt/anaconda3/share/jupyter/lab @jupyter-widgets/jupyterlab-manager v2.0.0 enabled OK keplergl-jupyter v0.2.0 enabled OK

I guess there are still some bugs when using jupyter lab in current version of keplergl(0.2.0), hope someone can fix it.
