Importing dask.distributed.Client causes `TypeError: unhashable type: 'types.SimpleNamespace'` (not using it)

See original GitHub issue

My alive_bar was working quite well for some time. Then, I implemented an optional branch in my program for parallel execution of some stuff using a Dask dataframe. In the course of implementing that branch, the alive_bar stopped working even in the serial-only branch. Turns out, it’s due to the import statement importing the dask.distributed.Client class. See my MWE below. Thanks!

import time
import dask
from dask.distributed import Client                        # this is the one that breaks alive_progress!
from alive_progress import alive_bar

total_reps = 100

with alive_bar(total=total_reps, force_tty=True) as bar:
    for i in range(total_reps):
        time.sleep(0.5)
        bar()

Thanks @chrsdrdt, but this ticket is specific for that Dask Client. The correct place would probably be #155. Please post it there, along with whether your setup might be reusing log handlers…

I do habe the same problem, running on version 2.4.1. If I run the code again, it works fine for the failed setting. I’m running my code several times, but it seems that it fails randomly
