working in jupyter lab? about ipyleaflet HOT 6 CLOSED

@paul-shannon jupyter widgets in jupyterlab is still the bleeding edge.
While most of the work is done, installation is still quite cumbersome. I will post some instructions.

from ipyleaflet.

@SylvainCorlay sorry to pester. I'll be grateful for those instructions when you find the time...

from ipyleaflet.

@paul-shannon no problem.

• So getting ipyleaflet to work in jupyterlab is quite cumbersome for now, since it requires installing ipywidgets from source and ipyleaflet from source
• Besides, the jupyterlab team is iterating quite rapidly and makes rapid releases with non-backward compatible version numbers (0.x.y) before the first 1.0.

Currently getting ipyleaflet in jupyterlab requires

1. jupyterlab 0.11.3.
2. The current state of master in ipywidgets
   • In jupyter-js=widgets, run npm install
   • In widgetsnbextension , run npm install then npm run update then pip install -e .
   • In ipywidgets run pip install -e .
   • In jupyterlab_widgets run npm install then npm run update then pip install -e .
   • jupyter labextension install --py --sys-prefix --symlink jupyterlab_widgets
   • jupyter labextension enable --py --sys-prefix jupyterlab_widgets
3. Install ipyleaflet from source
   • in js: npm install
   • at the root of the repo: pip install -e .
   • jupyter labextension install --py --sys-prefix --symlink ipyleaflet
   • jupyter labextension enable --py --sys-prefix jupyterlab_widgets

yay!

Many thanks @SylvainCorlay.

All steps went smoothly: thank you for laying them out.

There's a good lesson for me in this: despite your fine instructions, at the end of the process jupyter lab --log-level=0 gets me only a blank screen in the browser, with no contents in the html body of that page. I think I have come too early to jupyter lab development. The "alpha preview" should have warned me away.

Thanks again for your (and Jason's) kindly and patiently offered help. I will continue with ipywidget development in the notebook, returning to lab when the beta is released.

Thanks on (Gitter) , now we should be able to pip install jupyterlab,notebook, ipywidgets, and ipyleaflet (latest stable releases), and then jupyter labextension install @jupyter-widgets/jupyterlab-manager --no-build and then run npm install && jupyter labextension install . from the ipyleaflets/jslab folder.

#!/usr/bin/env bash

pip3 install --upgrade pip
pip3 install jupyter
pip3 install notebook
pip3 install jupyterlab
pip3 install ipywidgets
pip3 install ipyleaflet


jupyter labextension install @jupyter-widgets/jupyterlab-manager --no-build

git clone https://github.com/ellisonbg/ipyleaflet
cd ipyleaflet/jslab
npm install && jupyter labextension install .
cd ../..

jupyter nbextension enable --py --sys-prefix ipyleaflet

Note: I used npm from their own PPA (on ubuntu 16.04, with the default system python 3.5)

from ipyleaflet.

ipyleaflet now works in JupyterLab.

It can be installed by installing the pip package on the kernel side and running jupyter labextension install jupyter-leaflet for the lab extension.
