AttributeError: module 'concurrent' has no attribute 'futures'

[kardaj]

Hi, thanks for the project, the use case seems promising. I've been meaning to test it for a while and ended up installing python 3 to try it and run into this issue with all scripts:

$ aiotasks -vvvv worker -A examples.launch_manager_tasks_and_launch_in_console
Traceback (most recent call last):

Do you have any idea what I'm doing wrong or is there something broken?

[cr0hn]

What version of Python are you using?

[kardaj]

Python 3.6.2

[polosatyi]

@kardaj I think that you use python 2 by default. Type in console: python and check version.

If build from source in alpine all is Ok)

[kardaj]

@polosatyi just tried from another computer. I have the same error.

$ python --version
Python 3.6.3

[RomanKharin]

import concurrent.futures
import aiotasks

can help

[lttzzlll]

good good

[smlbiobot]

Looking for a library like this to replace celery but am getting the same issue.

For your info:

 $  python --version
Python 3.6.4

[shivammutreja]

I am using Python 3.5.2

This can be fixed by replacing import concurrent with import concurrent.futures in the following file.
/usr/local/lib/python3.5/site-packages/aiotasks/core/exceptions.py
If you're in a virtualenv you would find the following file here : path_to_virtualenv/lib/python3.5/site-packages/aiotasks/core/exceptions.py

But after this I get the following error -

Error in atexit._run_exitfuncs: Traceback (most recent call last): File "/usr/lib/python3.5/asyncio/tasks.py", line 239, in _step result = coro.send(None) File "/usr/lib/python3.5/asyncio/tasks.py", line 345, in wait fs = {ensure_future(f, loop=loop) for f in set(fs)} File "/usr/lib/python3.5/asyncio/tasks.py", line 345, in <setcomp> fs = {ensure_future(f, loop=loop) for f in set(fs)} File "/usr/lib/python3.5/asyncio/tasks.py", line 554, in ensure_future raise TypeError('A Future, a coroutine or an awaitable is required') TypeError: A Future, a coroutine or an awaitable is required

Please advise.

I am facing the same issue too.
FROM python:3.6-slim
my python version.

[gevorg-vardanyan-im]

Hi all,
I am using Python 3.7.9, I am getting above issue.
Here is my code block:
`import concurrent.futures
import time

start = time.perf_counter()

def do_smt(seconds=1):
print("sleep {seconds} sec".format(seconds=seconds))
time.sleep(seconds)
return 'Done something...\n'

with concurrent.futures.ProcessPoolExecutor() as executor:
f1 = executor.submit(do_smt, 1)
print(f1.result())

finish = time.perf_counter()
print('Finished in {} second(s)'.format(round(finish - start, 2)))`

And here is traceback:
File "<MY_FILE.py>", line 1, in <module> import concurrent.futures File "/usr/lib/python3.7/concurrent/futures/__init__.py", line 8, in <module> from concurrent.futures._base import (FIRST_COMPLETED, File "/usr/lib/python3.7/concurrent/futures/_base.py", line 7, in <module> import logging File "/usr/lib/python3.7/logging/__init__.py", line 40, in <module> import threading File "<MY_FILE.py>", line 13, in <module> with concurrent.futures.ProcessPoolExecutor() as executor: AttributeError: module 'concurrent' has no attribute 'futures'

Could you please help to solve this ?

Gevorg

Hi all,

about above comment - I use pycharm and I have been faced above issue.
As of now I have removed __pycache__ folder, removed all *.pyc files.
And now it works as expected.
So if you use an IDE, it might be helpful to remove all caches, and there is also one point in jetbrains products to remove caches.
You can open File -> invalidate caches / restart and do restart.

Regards,
Gevorg.
