I can't get widgets to work in python2 kernels in images built by repo2docker

See original GitHub issue

This repository:

https://github.com/simonsfoundation/jp_svg_canvas

attempts to use an environment.yml to set up a python 2 kernel with widgets enabled.

The image built by repo2docker results in a python 3 kernel with working widgets but widgets do not work in the python 2 kernel

I also tried other ways to get widgets working under repo2docker in Python 2 kernels, but I’m not having any luck 😦.

Tried to make a minimal example for this to reproduce the bug. So I made this repo which contains nothing but a runtime.txt with python-2.7 in it. When I launch a binder the only kernel available is Python 3. Discuss this: #280)

If you then add a requirements.txt you do get a Python 2 kernel. For this repo I added ipywidgets in requirements.txt.

I then added a Button widget in a notebook, which seems to work.

Same with an environment.yml instead of runtime.txt+requirements.txt: https://github.com/betatim/binder-widgets-py2/tree/f7a3e3fdb962a5ec317efdbec92676fdc96c9a0d this also seems to work.

From my side this means “can’t reproduce any more” -> got fixed. @AaronWatters could you confirm that the problem has gone away?
