Right now, the official date for ending support for Python 2.7 (and all of python2) is set to January 1 [1]. As part of it, a number of projects have pledged to drop support for Python2 in or before 2020 including Tensorflow, requests, pandas, ipython, numpy, pillow, and Cython [2]. I believe we should also join in this pledge on python3statement.org [2] because it would help clean up our project and it would be difficult to continue supporting Python2 anyway when some of our dependencies are dropping support.
As a concrete step, we should decide on a date to remove all usages of Python2 from our CI and consider that officially dropping support. Following that, we can expect PRs will end up breaking support for Python2. I suggest just using the same date that Python is dropping support of January 1. We may also need to update some examples or scripts that were written only for python2 that are around the project. Any thoughts?
