[users at bb.net] py2 master <==> py3 worker, problem

[Craig Rodrigues]

Hi,

>From the buildbot master branch, I experimented with setting up
a Python 2.7 master and a Python 3.6 worker.  I was able to start the
master and worker,
and saw that they connected to each other.

However, when I triggered a build, I got:


Traceback (most recent call last):
  File

704, in run
    results = yield self._start_deferred
buildbot.process.remotecommand.RemoteException: buildbot_worker.base.
UnknownCommand: unrecognized WorkerCommand 'b'shell''
Traceback unavailable


Any ideas what the problem could be?
