Hi,
I am getting this error while trying out the FigureWidget. I am getting the error on both Jupyter Lab and Jupyter Notebook.
On the browser dev console:
Error displaying widget
Module plotlywidget, semver range ^0.1.1 is not registered as a widget module
Any help will be greatly appreciated as Iâve been googling and searching for an answer but to no avail.
Hi @vhphan,
Did you follow all of the installation instructions in the README at https://github.com/plotly/plotly.py? There are several packages with particular versions that you need to get FigureWidget working.
-Jon
Did the following (from the README). I still couldnât make it work. 
pip install plotly==3.1.0
pip install ânotebook>=5.3â âipywidgets>=7.2â
jupyter nbextension enable --py widgetsnbextension --sys-prefix
jupyter nbextension enable --py plotlywidget --sys-prefix
Hi @vhphan,
Can you double check that you have the specified versions of JupyterLab and the JupyterLab extensions installed as well?
pip install jupyterlab==0.32.1
export NODE_OPTIONS=--max-old-space-size=4096
jupyter labextension install @jupyter-widgets/jupyterlab-manager@0.35 # install the Jupyter widgets extension
jupyter labextension install plotlywidget@0.2 # FigureWidget support
jupyter labextension install @jupyterlab/plotly-extension@0.16 # offline iplot support
If things still arenât working, please post the result of running pip list and jupyter labextension list in your environment.
Thanks!
I have the same problem:
//
After installing the labextensions, still some errors appear:
Could not instantiate widget
Error: Could not create a model.
Uncaught (in promise) Module plotlywidget, semver range ^0.1.1 is not registered as a widget module

jupyterlab-launcher 0.10.5
notebook 5.4.0
plotly 3.0.2
Any ideas? 
Hi @komeyer,
It looks like youâre version of plotly (python) and plotlywidget (JupyterLab) are out of sync. Upgrade plotly.py to 3.1.0 (which corresponds to plotlywidget version 0.2.0 which you already have).
@vhphan can you check these version numbers too?
The versions numbers between the python library and the JupyterLab extensions have to line up (they are specified in the README), and unfortunately thereâs not a way to enforce that the Python and JupyterLab packages do this automatically.
Thanks!
Thanks a lot @jmmease , upgrading to plotly to 3.1.0 was the solution! 
Just for my unterstanding: Which version numbers have to line up? Now I have:
jupyterlab 0.32.1
plotly 3.1.0
plotlywidget 0.2.0Great!
So the versions of jupyterlab (Python) and @jupyter-widgets/jupyterlab-manager (JavaScript) have to line up according to the versions listed here: https://github.com/jupyter-widgets/ipywidgets/tree/master/packages/jupyterlab-manager. This is what you need to do to get basic ipywidgets working (sliders, etc.).
For the plotly FigureWidget support you need the plotly (Python) and plotlywidget (JavaScript) versions to line up according to our README/changelog (currently 3.1.0 and 0.2.0 respectively).
The @jupyterlab/plotly-extension (JavaScript) extension is needed for offline iplot support. This shouldnât need to be updated as frequently.

Hi @vhphan,
If youâre still struggling with this, could you include your updated browser error message? The packages you have installed look good, but if you still have an error Iâd like to see what widget version itâs complaining about.
Thanks,
-Jon
Hmm, ok.
A couple of thoughts. Are you able to display non-plotly ipywidgets? For example, do you see a slider when you run this code?
import ipywidgets
ipywidgets.IntSlider()
Another thought: I think I remember hitting a 404 error at one point (across all ipywidgets) when had a an adblock extension update. So if you have an adblock extension make sure to whitelist localhost. Also try it in multiple browsers (at least chrome and firefox), and make sure the browser versions are up to date.
Sorry, I know this is a scattershot of suggestions. Thanks for sticking with it!
-Jon
Thanks for trying.
I could display non-plotly widgets.
I tried on another browser (Firefox) but still got the same errors in the browserâs console.
Hmm, sorry Iâm running out of ideas.
What I would try next is to try creating a fresh conda environment for the installation
$ conda create -n plotlywidget python=3.6
$ conda activate plotlywidget
$ pip install plotly==3.1.1
$ pip install "notebook>=5.3" "ipywidgets>=7.2"
$ pip install jupyterlab==0.33
$ export NODE_OPTIONS=--max-old-space-size=4096
$ jupyter labextension install @jupyter-widgets/jupyterlab-manager@0.36 --no-build
$ jupyter labextension install plotlywidget@0.2.1 --no-build
$ jupyter labextension install @jupyterlab/plotly-extension@0.16 --no-build
$ jupyter lab build
$ jupyter lab # launch and try again
-Jon
I had the same issue as @vhphan and the fix was, as you suggested, to strictly match versions as described in the README/Changelog (e.g. https://github.com/plotly/plotly.py/blob/master/CHANGELOG.md#jupyterlab-versions for latest plotly 3.4.0).
Hi, I am getting similar error as vhphan and not sure how to fix it since I thought I have matched all the versions.
here is what I have:
JupyterLab v0.35.3

app dir: C:\Users\snamnaba\AppData\Local\Continuum\anaconda3\share\jupyter\lab

jupyterlab-chart-editor v1.0.0 enabled ok
jupyterlab-flake8 v0.2.4 enabled ok

Build recommended, please run jupyter lab build:
plotlywidget needs to be included in build

Hi @soha,
I looks like the problem is that the JupyterLab package manager doesnât think it has internet access.
info There appears to be trouble with your network connection. RetryingâŚ
Are you connected to the internet during the build process?
If so, it might also be worth trying to install nodejs using conda and then rebuilding
$ conda install nodejs
$ jupyter lab build
-Jon
yes I do have access to the internet at all times when I tried to build Jupyterlab. Though I donât know why it always give that error. I also tried cloning my environment and rebuild jupyter lab but still faced same issue.
