Same problem with
Ray 1.7.0
aiohttp 3.8.0
Python 3.9.5
macOS Big Sur

import aiohttp.signals
from aiohttp.frozenlist import FrozenList  # noqa: F401

fail with aiohttp 3.8.0 which is permitted by ray/python/requirements.txt which says aiohttp>=3.7

Getting the same problem due to aiohttp 3.8.0 that released breaking changes :(

Yes, that is why simple downgrading ray does not help.

[dennymarcels]

Same.
Ray 1.8 and 1.7
Python 3.9
Debian 11

I confirm that downgrading aiohttp to 3.7 solves it temporarily.

I confirm that downgrading aiohttp to 3.7 solves it temporarily.

This should be reflected in ray/python/requirements.txt:
Instead of "aiohttp>=3.7" something like "aiohttp==3.7".

This works! Even inside docker as well

I think this issue was fixed when PR #20261 landed on master.
