Missing icons in jupyterlab

[wdalrymple]

Issue: Icons missing from tree in JupyterLab

• Icons render as 'empty' images (i.e. blank squares). I am guessing that the CSS is buggered.

Here is code to reproduce this:

from ipytree import Node, Tree

tree = Tree()

 

root_node = Node('Root 1', opened = False)

tree.add_node(root_node)

new_child = Node('Child 1')

new_child.model = 1

root_node.add_node(new_child)

 

root_node = Node('Root 2', opened = False)

tree.add_node(root_node)

new_child = Node('Child 2')

new_child.model = 1

root_node.add_node(new_child)

 

tree

setup for jupyterlab:

JupyterLab v2.1.4

Known labextensions:

   app dir: /opt/app-root/share/jupyter/lab

        @j123npm/jupyterlab-dash v0.1.0-alpha.4  enabled  OK

        @jupyter-widgets/jupyterlab-manager v2.0.0  enabled  OK

        @jupyterlab/debugger v0.3.0-alpha.1  enabled  OK

        @jupyterlab/git v0.20.0  enabled  OK

        @jupyterlab/latex v2.0.0  enabled  OK

        ipytree v0.1.8  enabled  OK

        jupyterlab-plotly v4.8.0  enabled  OK

        jupyterlab-sql v0.3.3  enabled   X

        plotlywidget v4.8.0  enabled  OK

        qgrid2 v1.1.3  enabled  OK

 

   The following extension are outdated:

        jupyterlab-sql

       

   Consider running "jupyter labextension update --all" to check for updates.

I cannot reproduce locally. Installing JupyterLab 2 with latest ipytree seems to work properly. Do you see any error in the JavaScript console?

Hi I didn't make it clear that I was experiencing this issue in Jupyterhub with JupyterLab. That is probably the reason why you were not able to reproduce it.

And there were no issues in the console

And there were no issues in the console

Not even a 404 error? Do you see any other missing icons in the JupyterLab UI? FontAwesome might not be in the page :S But I am not sure. JupyterLab should include it in the page.

Nothing. It's odd for sure
