PBSControllerLauncher broken in 7.1.0

[lukas-koschmieder]

PBSControllerLauncher appears to be broken in 7.1.0 because the attribute/method poll is not implemented.

ipyparallel raises an exception AttributeError: 'PBSControllerLauncher' object has no attribute 'poll' at

ipyparallel/ipyparallel/cluster/launcher.py

Line 344 in 527d7b2

status = self.poll()

You can use the following code to replicate the error.

import ipyparallel as ipp
rc=ipp.Cluster(
    n=4, 
    controller_ip='*', 
    controller_launcher_class='ipyparallel.cluster.launcher.PBSControllerLauncher', 
    engine_launcher_class='ipyparallel.cluster.launcher.PBSEngineSetLauncher',
    profile='pbs'
).start_and_connect_sync()

Stdout:

Job submitted with job id: '23736'
Starting 4 engines with <class 'ipyparallel.cluster.launcher.PBSEngineSetLauncher'>

    343             await asyncio.sleep(0.1)
--> 344             status = self.poll()
    345             if inspect.isawaitable(status):
    346                 status = await status
