I am using Pydroid to code in android. Though it is an ARM machine so I downloaded OpenCV-python wheel from PiWheels and successfully installed it using pip. But i can't import OpenCV anyways. Please help.
Here is what I tried:
/storage/emulated/0 $ pip list

The name of the module is cv2.
Try import cv2 .
When I faced a similar problem in my laptop, installing opencv in a Conda environment did the job for me. Try removing opencv and try reinstalling it.
