import plotly.graph_objects fails with ipywidget version is <= 7.0.0

[GaelVaroquaux]

Steps to reproduce:

$ python3.7 -m venv test
$ . test/bin/activate
(test) $ pip install plotly
(test) $ pip install ipywidgets==6
(test) $ python -c "import plotly.graph_objects"
Traceback (most recent call last):
  File "", line 1, in 
  File "/home/varoquau/tmp/clean_venv/test/lib/python3.7/site-packages/plotly/graph_objects.py", line 2, in 
    from plotly.graph_objs import *
AttributeError: module 'plotly.graph_objs' has no attribute 'FigureWidget'

The problem is on line 100184 of plotly/graph_objs/init.py: the __all__.append("FigureWidget") that is a few lines below should be moved under the "if" clause.

Given that it is generated code, I don't know how to fix it, so I won't send a pull request.

Indeed, we don’t support anything below 7.2.

Sorry, that’s actually 7.2 for classic Notebook and 7.5 for Jupyter Lab, according to our docs at https://plot.ly/python/getting-started/

🤦‍♂ sorry, I misread your issue. Importing should not fail, clearly :)

Importing should not fail, clearly :)

Thanks, I was hesitating with replying that, wondering if I was being an A-hole. :)

Nope that was me ;)
