data collection does not seems to work :( about depthai-experiments HOT 8 OPEN

Hi @abhatikar, thanks for submitting the issue and sorry for my late response, I must have missed the notification.

I've updated the data collecting script, and it should work much better now, the issue you've posted should also be fixed.

Could you try the latest version if it works on your side?

from depthai-experiments.

If it still does occur please reopen this issue - thanks!

from depthai-experiments.

I tried to run this but got the same error I think.

Is it perhaps the API version in the requirement.txt file that is old or something?

upon running python main.py (after installing requirements etc)

I got the following output.

Camera seems to work fine with most of the other experiment examples.

from depthai-experiments.

Thanks for checking @jonititan, indeed I incorrectly handled the None case of the -af flag. This PR should resolve this issue, tested it on my side and it works now

from depthai-experiments.

Thanks for that it does run now that autofocus flag issue is sorted but doesn't capture frames. Some sort of write error.
cv2.imshow never triggers and no frames get displayed.

See a section of the output.

@jonititan Seems like a device issue, could you try to unplug the device and plug it back again, with USB cable attached directly to the host (not via e.g. USB hub)
And CC @themarpe in case you see something relevant here

from depthai-experiments.

You're quite correct.

Moved from hub and it started logging perfectly for a little while and then had segfault. Apologies thats probably an unrelated issue.

Edited to add: I ran it a couple more times and it hasn't segfaulted again so far. I'll continue testing but i think that may be unrelated.
Thanks for your help
