OAK-D W PoE - Depth Viewer displays nothing

Same problem on Windows 11, same pink and red flashing rectangles. I'm running from DepthAI-setup-v3.5.0.exe, which installed depthai-viewer 0.2.2 and NumPy 2.0.0.

Console repeatedly prints:

WARNING:root:Ignoring rerun log call: Traceback (most recent call last):
  File "C:\Users\bill\AppData\Local\Programs\DepthAI\venv\lib\site-packages\depthai_viewer\log\log_decorator.py", line 35, in wrapper

    colors_array = np.array(colors, copy=False)
ValueError: Unable to avoid copy while creating an array as requested.
If using `np.array(obj, copy=False)` replace it with `np.asarray(obj)` to allow a copy when needed (no behavior change in NumPy 1.x).
For more details, see https://numpy.org/devdocs/numpy_2_0_migration_guide.html#adapting-to-changes-in-the-copy-keyword.

Making the suggested change results in the image below and these changes to behavior:

• App no longer prints any errors to the console.
• 3D view still flashes a pink image, but the image now has rings around the center.
• The depth cameras still flash pink and red as above, but there are now green boxes identifying things, and the big box moves around as I lean left and right.

Removing the other 2 occurrences of copy=False exhibits no further change.

One more edit: Using Luxonis' own "Oak as webcam" program demo exposed a similar problem within pyvirtualcam. Downgrading NumPy to 1.26 fixed the problem there. However, I did this from within a separate virtualenv containing depthai installed from Pip. This version of depthai-viewer does not contain the copy=False lines from above, and yet exhibits the exact same pink windows as above. Downgrading NumPy had no effect on this bug.

So to summarize, steps to reproduce are:

pipenv shell
pipenv install numpy==1.26 depthai depthai-viewer
depthai-viewer

Hey guys, I will fix the issue on the viewer right now. It's caused by the release of Numpy 2.0.0 which breaks the ABI, this causes undefined behaviour on depthai, like you have experianced... You can fix other examples by installing a version of numpy < 2.0.0, like @wrzwicky already posted above. @wrzwicky The reason why installing a lower version of numpy did not solve the issue on the viewer is because the viewer creates it's own venv.
