Slider is not displayed in Jupyterlab, shows IntSlider(value=0) instead

[hans-permana]

Hi all,

It is part of my learning process in installing ipywidgets on my Jupyterlab that I browsed through the issues in this repository (open and closed). However, I could not find one to fix my current issue.

I have successfully installed ipywidgets using conda install but when trying to display a slider using an instruction from this guide, it does not give me the slider I wanted. Instead, it shows me IntSlider(value=0) instead. What's the trick here?

Here is some information about my environment:
ipywidgets: 7.3.0
widgetsnbextension: 3.1.4
jupyterlab: 0.32.1
jupyter labextension list

node: 8.10.0

The JLab widgets plugin doesn't support 7.3 yet. Downgrade to 7.2.1. We're waiting until jlab 0.33 next week for 7.3 support.

Unfortunately downgrading to 7.2.1 does not solve the problem.

While downgrading to 7.2.1 using this command conda install -c conda-forge ipywidgets=7.2.1 I observed that my widgetsnbextension was upgraded to 3.2.1. Possibly because previously it was the conda package from anaconda channel.

Downgrading to 7.2.1 did actually solve the problem. I just needed to reload my Jupyterlab page after downgrading it. Thanks for the help!
