Try to change this:
with dai.OakCamera(pipeline, maxUsbSpeed=dai.UsbSpeed.HIGH) as oak:

To with dai.Device(pipeline, maxUsbSpeed=dai.UsbSpeed.HIGH) as oak:

@filipjeretina

The problem I think is partly due to it being ran through a USB2, I just need the lag time for this to be reduced and for the device to stop crashing.

It seems to crash pretty quickly once a person is in front of the camera

But also, please send the contents of this file:
C:\Users\sale4088\AppData\Local\Programs\Depthai2\depthai-viewer\scripts\depthai-experiments\gen2-people-tracker\main.py

@filipjeretina

I have been sending the contents of that file, the folder is the same as the tab in the github, I cloned that github and have been editing from the exact files that are in it.

Okay so this is the file you are running:

#!/usr/bin/env python3

from depthai_sdk import OakCamera, TrackerPacket, Visualizer, TextPositionimport depthai as daifrom people_tracker import PeopleTrackerimport cv2
pt = PeopleTracker()
with OakCamera() as oak:    color_cam = oak.create_camera('color')    tracker = oak.create_nn('person-detection-retail-0013', color_cam, tracker=True)    tracker.config_nn(conf_threshold=0.6)    tracker.config_tracker(tracker_type=dai.TrackerType.ZERO_TERM_COLOR_HISTOGRAM, track_labels=[1])
    def cb(packet: TrackerPacket, vis: Visualizer):        left, right, up, down = pt.calculate_tracklet_movement(packet.daiTracklets)
        vis.add_text(f"Up: {up}, Down: {down}", position=TextPosition.TOP_LEFT, size=1)        vis.draw(packet.frame)
        cv2.imshow('People Tracker', packet.frame)
    oak.visualize(tracker.out.tracker, callback=cb)    oak.start(blocking=True)

I was just confused with the error you sent here:

michaelsalerno

Maybe you can try to lower the fps on the camera:

color_cam = oak.create_camera('color', fps=10)

    @filipjeretina

    I think it is now working

    Thank you for all your help

    My apologies if I was short tempered, I was extremely nervous for tomorrows meeting and needed everything to be working well.

    Thank you again

    My apologies if I was short tempered, I was extremely nervous for tomorrows meeting and needed everything to be working well.

    hahah, I get it. Really sorry for the inconvenience. But for the future. NEVER work inside of the installers repository.... It is not safe!!! And make backups of things!

    Wait, it seems to be not working again

    What is the issue now?

    I removed the versions since I wanted it to function and not be confined to a certain version, but maybe Ill try adding it back?

    This seems like an environment error
    Not sure why, but make sure you have depthai_sdk installed.
    can install it via python -m pip install depthai_sdk

    I removed the versions since I wanted it to function and not be confined to a certain version, but maybe Ill try adding it back?

    Yea

    I would suggest you to copy the working version to your Desktop and leaving it alone. Maybe also run python -m pip freeze which will give you a list of all installed packages. And save this somewhere too.
