Hello,
I am running depthAi version 2.20.2.0 which should be the latest as of 2/6.. I just did a git pull to refresh...
When I run depthai_demo.py, I just get the attached screens... I don't see the QT demo screen as shown in the docs.

also when the demo program runs i get this error before the attached screens appear:
ImportError: cannot import name 'Previews' from 'depthai_sdk' (/home/hchattaway/.local/lib/python3.10/site-packages/depthai_sdk/init.py)
Sentry is attempting to send 2 pending error messages
Waiting up to 2 seconds
Press Ctrl-C to quit
Error while running demo script... Command '"/usr/bin/python3" depthai_demo.py --noSupervisor --guiType qt' returned non-zero exit status 1.
Thanks for any help!
BTW, I am running this on Ubuntu 22.04 LTS

    I just did a pull to get the latest update from the PR.. and at first, it gave the same error...
    But then I checked the location of init.py file that was referenced in the error message above which is here: /home/hchattaway/.local/lib/python3.10/site-packages/depthai_sdk/

    So I updated the init python program there with the 2 new lines and then it worked... But what step would have placed the files there initially? I always cloned the repo..

    Thanks for the quick fix!

      Hi hchattaway ,
      Sorry about that, after checking out the PR you need to install the depthai-sdk by calling pip install ./depthai_sdk.
      Thanks, Erik

        Ah, ok.. that makes sense.. so after each new git pull run that to properly install update.

        Thanks
        Harold
