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 I’ve 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](https://github.com/plotly/plotly.py)? There are several packages with particular versions that you need to get `FigureWidget` working.

Did the following (from the README). I still couldn’t make it work. ☹

pip install plotly==3.1.0  
pip install “notebook\>=5.3” “ipywidgets\>=7.2”

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?

```auto
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 aren’t working, please post the result of running `pip list` and `jupyter labextension list` in your environment.

Thanks!

Hi @komeyer,

It looks like you’re 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 there’s 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 0.2.0
```

Great!

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](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 shouldn’t need to be updated as frequently.

Hi @vhphan,

If you’re 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 I’d like to see what widget version it’s 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?

```python
import ipywidgets
ipywidgets.IntSlider()

```

![56%20AM](https://us1.discourse-cdn.com/flex024/uploads/plot/original/2X/2/2a00f80ee70d1d3a06afe3bb03e6db80017c95f0.png)

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!

Thanks for trying.

I could display non-plotly widgets.  
I tried on another browser (Firefox) but still got the same errors in the browser’s console.

Hmm, sorry I’m running out of ideas.

What I would try next is to try creating a fresh conda environment for the installation

```auto

$ pip install "notebook>=5.3" "ipywidgets>=7.2"
$ pip install jupyterlab==0.33

$ 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

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](https://github.com/plotly/plotly.py/blob/master/CHANGELOG.md#jupyterlab-versions) for latest plotly 3.4.0).

Hi @soha,

I think this part might be the key. What happens when you run `jupyter lab build` from the command line?

Hi @soha,

I looks like the problem is that the JupyterLab package manager doesn’t think it has internet access.

> info There appears to be trouble with your network connection. Retrying…

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

```auto
$ conda install nodejs
$ jupyter lab build

```

yes I do have access to the internet at all times when I tried to build Jupyterlab. Though I don’t know why it always give that error. I also tried cloning my environment and rebuild jupyter lab but still faced same issue.
