when I execute px.scatter(gapminder2007, x="gdpPercap", y="lifeExp") I got an error in browser and nothing is showed in jupyterlab, but place for graph is reserved:

In the same notebook plotly works, for example:
import plotly.graph_objs as go
from plotly.offline import download_plotlyjs, init_notebook_mode, plot, iplot
plot([go.Scatter(x=[1, 2, 3], y=[3, 1, 6])])
OS: Linux Manjaro
Browser: Firefox 66.0.1 (64-bit)
plotly: 3.7.1
plotly_express: plotly_express.
version
doesn't work, I don't know how to check
jupyterlab: 0.35.4
jupyterlab/plotly-extension: I don't know how to check version, but I have just installed it today
Looks like I forgot to execute:
`# Avoid "JavaScript heap out of memory" errors during extension installation
(OS X/Linux)
export NODE_OPTIONS=--max-old-space-size=4096
(Windows)
set NODE_OPTIONS=--max-old-space-size=4096
Jupyter widgets extension
jupyter labextension install @jupyter-widgets/[email protected] --no-build
FigureWidget support
jupyter labextension install [email protected] --no-build
offline iplot support
jupyter labextension install @jupyterlab/[email protected] --no-build
JupyterLab chart editor support (optional)
jupyter labextension install [email protected] --no-build
Build extensions (must be done to activate extensions since --no-build is used above)
jupyter lab build
Unset NODE_OPTIONS environment variable
(OS X/Linux)
unset NODE_OPTIONS
(Windows)
set NODE_OPTIONS=`
...as it is stated on page
https://github.com/plotly/plotly.py/blob/master/README.md
in section "JupyterLab Support (Python 3.5+)"
Now everything works. I hope this information will help to someone.
