We dont plan to drop python 2.7 yet.
The last time we discussed this, we thought about dropping it when either of the two happens:

We see < 10% Python 2.7 downloads
The pain threshold for maintaining 2.7 support is so great that PyTorch as a product loses significant development time

Neither of them have happened, or are expected to happen by June of next year as far as I can tell.
My answer, as you see, is not giving you a commitment, but giving you the thought process of the team.
We haven’t committed to an LTS release at this point (we aren’t even 1.0 stable until December this year)
