Simple task raises OSError and addresses should be strings or tuples

See original GitHub issue

I’ve created functions and submitted them to the dask client on my work machine without a problem. Similar code on my home machine results in behavior or errors I don’t understand. Both machines have 6+ cores and use Windows 10, Anaconda Python 3.7 64 bit, and PyCharm. For example, this code:

from distributed import Client, wait
from random import randint

def dask_task(num_nodes):
	ids = {}
	for n in range(num_nodes):
		this_id = "V" + str(randint(0, 1000))
		ids[n] = this_id
	return ids


dask_client = Client(processes=False)
result = {}
for task_num in range(5):
	result[task_num] = dask_client.submit(dask_task, 100)
wait(result)
dask_client.close()

Results in a dictionary of cancelled futures:

result
{0: <Future: cancelled, type: builtins.dict, key: dask_task-7a742226fc2608487c29a8e88eace65c>, 1: <Future: cancelled, type: builtins.dict, key: dask_task-7a742226fc2608487c29a8e88eace65c>, 2: <Future: cancelled, type: builtins.dict, key: dask_task-7a742226fc2608487c29a8e88eace65c>, 3: <Future: cancelled, type: builtins.dict, key: dask_task-7a742226fc2608487c29a8e88eace65c>, 4: <Future: cancelled, type: builtins.dict, key: dask_task-7a742226fc2608487c29a8e88eace65c>}

Running the code with Client() instead of Client(processes=False) throws a long trace, which looks like a path error or bad character (OSError: [Errno 22] Invalid argument) but I’ve never encountered it before in this project.

FWIW, I’m experiencing the same problem when running dask in a Jupyter Lab session (running a notebook) on a SLURM cluster.

@CMCDragonkai I’m more asking how does this error:

raise TypeError("addresses should be strings or tuples, got %r" % (addr,))

Occur?

There’s no addresses that I’m aware of here.

If you could explain what exactly is this address that it’s complaining about? It looks like a small type error somewhere that I can investigate further.
