 Priority:  normal              |      Milestone:  Support Python 3
Component:  dev-infrastructure  |        Version:  n/a

--------------------------------+----------------------------------
 A new release of attrs (20.1.0, August 20) has dropped Python 2, so
 `misc/python3/tahoe-depgraph.py` isn't working anymore.

 https://app.circleci.com/pipelines/github/tahoe-lafs/tahoe-
 lafs/686/workflows/5db2ada2-de6f-40d1-9005-df97dc6b3bdd/jobs/26870

 We will have to use an upper bound, and then drop the upper bound when
 we're ready.
