Preview Window Not showing

OzayrMoorad

Hi, when i run scripts from depth-experiments using the depthai package I get a preview window however when running the examples using depth_sdk with the visualiser i get not preview window. Im on macOS.

I checked OpenCV imshow and it works fine. not sure what the issue is.

Hi OzayrMoorad
Might be that you have problems with opencv-contrib or pyQt5. Could you try running cam_test.py script to see if you get an error for GUI?

Thanks,

I am also having a problem with the preview window not showing. My scenario is as follows:

I have code similar to the "hello world" example. I run the script as python3 main.py and the preview window pops up. I press "q" to terminate the infinite loop and am able to obtain and process the image.
Now I have included the code in a very simple, basic web app using Flask. The code runs but the preview window does not pop up, so no image is captured.

I am running on MacOS. I am allowing pop_up windows on my web page so that does not seem to be the problem. Any advice is appreciated.

Hi ChristopherNichols
Could you explain a bit how your code works? I'm confused as to what popup has to do with cv.Imshow().

Thanks,
