RuntimeError: module compiled against API version 0xe but this version of numpy is 0xd
Traceback (most recent call last):
File "//home/pi/adeept_picarpro/server/webServer.py", line 26, in
import app
File "/home/pi/adeept_picarpro/server/app.py", line 8, in
from camera_opencv import Camera
File "/home/pi/adeept_picarpro/server/camera_opencv.py", line 2, in
import cv2
File "/usr/local/lib/python3.9/dist-packages/cv2/init.py", line 5, in

It may be that the Raspberry Pi version compatibility problem causes the dependent library to fail to be installed successfully. Please download and install Raspberry Pi OS (Legacy).
Raspberry Pi OS (Legacy) download address: https://www.raspberrypi.com/software/operating-systems/
You need to find ”Raspberry Pi OS (Legacy)“ in the link and download the image file.

In this essay, you make some compelling arguments. Without this, I never would have thought to evaluate any of anything. Much obliged.
