Only "Loading widget..." but no Matplotlib figures (fresh install with conda)

See original GitHub issue

Fresh install with conda (laptop with Ubuntu 18.04 => nothing to do with Docker).

Maybe related to #161 ?

Matplotlib figures do not show up and I get only

Loading widget...
[<matplotlib.lines.Line2D at 0x7fa9e8358e50>]

Standard installation with conda:

conda install -c conda-forge ipympl nodejs
jupyter labextension install @jupyter-widgets/jupyterlab-manager jupyter-matplotlib

jupyter labextension list
JupyterLab v1.2.5
Known labextensions:
   app dir: /home/marianne/miniconda3/share/jupyter/lab
        @jupyter-widgets/jupyterlab-manager v1.1.0  enabled  OK
        jupyter-matplotlib v0.5.0  enabled  OK

Note that ipywidgets seems to work fine. from ipywidgets import Button; Button(description='test') gives a button.

Hi @thomasaarholt, Unix, more specific:

> lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 18.04.4 LTS
Release:	18.04
Codename:	bionic

Yah, I should say that I installed more Conda packages then first stated, as it is probably some of their dependencies which makes Conda downgrade the ipymlp version. I tried to install all these packages, which works: conda create -n py37_jupyterlab_v2.1.5 python=3.7 jupyterlab nb_conda_kernels nodejs nbresuse flake8 jupyterlab_code_formatter black ipympl==0.5.6 nbdime dask-labextension jupyterlab-git pandas holoviews

And for setting up the JupyterLab extensions: conda activate py37_jupyterlab_v2.1.5; jupyter labextension install @ijmbarr/jupyterlab_spellchecker@0.1.6 @jupyter-widgets/jupyterlab-manager@2.0.0 @jupyterlab/geojson-extension@2.0.1 @jupyterlab/git@0.20.0 @jupyterlab/github@2.0.0 @jupyterlab/shortcutui@0.5.0-beta.2 @jupyterlab/toc@4.0.0 @krassowski/jupyterlab_go_to_definition@1.0.0 @pyviz/jupyterlab_pyviz@1.0.4 @ryantam626/jupyterlab_code_formatter@1.3.1 dask-labextension@2.0.2 jupyterlab-flake8@0.6.1 jupyterlab-python-file@0.4.0 nbdime-jupyterlab@2.0.0 --no-build; jupyter lab build; jupyter serverextension enable --py jupyterlab_code_formatter; jupyter serverextension enable dask_labextension
