What happened + What you expected to happen

Unable to start head node with dashboard

Versions / Dependencies

version: ray[default]==1.7.0

Reproduction script

Reproduce steps:
machine: Linux 4.15.0-88-generic x86_64

 conda create -n ray python=3.8.11
 conda activate ray
 pip install ray[default]==1.7.0
 IP=`hostname -I | awk '{print $1}'`
 ray start --head --port=6379 --node-ip-address="$IP" --redis-password="1" --include-dashboard=true  -- dashboard-port=8266 --dashboard-host "0.0.0.0"

this command fails to start with the following error

    raise ImportError(DASHBOARD_DEPENDENCY_ERROR_MESSAGE)
    ImportError: Not all Ray Dashboard dependencies were found. To use the dashboard please install Ray using `pip 
    install ray[default]`

The same installation two weeks ago on another machine works like a charm.
When I copied the exact env from the old machine it working. When I do the following installation steps on another machine it fails. So my suspicion is that the latest buggy version is released
Please take a look

Anything else

It happens for me for every new installation

Ah, this may be because of a recent aiohttp issue. Can you try running pip install aiohttp<3.8?

[sjulias]

You absolutely right,
I've run pip install aiohttp==3.7 , and now it is working
Thank you very much!!!
