dash on Jupyterlab running in docker #39
Description
I'm running the python data science notebook docker image.
I tried enabling the dash extension from jupyterlab's extension manager, which did not work for me.
I also tried following the instructions at: https://github.com/plotly/jupyterlab-dash#installation
That also did not work.
Can someone please guide me on how to set it up in the environment I am using ?
The code I've run is:
!pip install jupyterlab_dash
!jupyter labextension install [email protected]
!jupyter labextension install jupyterlab-dash
# eveyrthing installs successfully
import jupyterlab_dash
import dash
import dash_html_components as html
viewer = jupyterlab_dash.AppViewer()
app = dash.Dash(__name__)
app.layout = html.Div('Hello World')
viewer.show(app)
Output:
Exception in thread Thread-105:
Traceback (most recent call last):

OSError:
Unable to communicate with the jupyterlab-dash JupyterLab extension.
Is this Python kernel running inside JupyterLab with the jupyterlab-dash
extension installed?
You can install the extension with:
$ jupyter labextension install jupyterlab-dash
