Research direction

Start in ipython_cleanup.py at cleanup_all and compare its IPythonClient instantiation with the Client(profile='distarray') setup shown in the reproduction. Run the profile, controller, engine, and script steps to confirm the failure; done means cleanup works with a non-standard Client profile without falling back to the default profile.

Written by the indexing model from the issue text.

Description

Problem

The IPythonClient instantiation in cleanup_all in ipython_cleanup.py is problematic since the default profile is used:

def cleanup_all(module_name, prefix):
    """ Connects to all engines and runs ``cleanup()`` on them. """
    c = IPythonClient()
    if c is None:
        return
    try:
        v = c[:]
        cleanup(v, module_name, prefix)
    finally:
        c.close()

Steps to Reproduce

Create a new ipython profile distarray

$ ipython profile create --parallel --profile=distarray

Start up controller

$ ipcontroller --ip='*' --profile=distarray

and engine

$ ipcluster engines -n 1 --profile=distarray

The run the following script

import numpy as np

import distarray.globalapi

from distarray.globalapi import Context, Distribution
from distarray.globalapi.ipython_utils import IPythonClient as Client

context = Context(client=Client(profile='distarray'))
