OpenMV M7 AttributeError about image read/write

Hi, I’m trying OpenMV in our course project. I want to record a video when field visit for later test.
But the problem is when i tried the function, it showed no attribute in these cases. Btw, mjpeg module works but i cannot find an alternative read module.
I’m quite confused about that, could you help me?

I don’t understand what you mean here? The ImageReader/Writer was removed. It’s ImageIO now: image — machine vision — MicroPython 1.13 documentation
