OpenCV-python not importing

Question

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:

Answer 1

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.
