Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

Looks like there may be a number of jupyter extension related dependencies that need to be incorporated: https://github.com/plotly/plotly.py/compare/v3.0.2...master

These are the current instructions in the 3.1.0 readme where notebook, ipywigdets, and jupyterlab are listed a dependencies:

Installation of plotly.py Version 3

To install plotly.py and enable Jupyter or Jupyter Lab support, run:

pip install plotly==3.1.0
pip install "notebook>=5.3" "ipywidgets>=7.2"  # only necessary for Jupyter Notebook environments

If you're using older versions of notebook or ipywidgets you may need to manually activate the widget extensions (this should not be needed for notebook>=5.3 and ipywidgets>=7.2)

jupyter nbextension enable --py widgetsnbextension --sys-prefix
jupyter nbextension enable --py plotlywidget --sys-prefix

In addition, to add JupyterLab support run the following commands

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

There are also a number of optional dependencies listed here:

https://github.com/plotly/plotly.py/blob/master/optional-requirements.txt

That we should possibly add.

The tox.ini file shows the optional dependencies more clearly: https://github.com/plotly/plotly.py/blob/master/tox.ini#L53

Let's go with the minimum dependencies instead of listing all possible optional ones.

Ok, but one of the big updates for plotly 3 was the jupyter(lab) integration. So users will have to figure out how to get that all setup themselves. That's why I brought up these dependencies.
