Answer 1

So it started working in mine after I did these:

1. First I went to https://pypi.org/project/aruco/#description I downloaded their zip file by clicking on 'Download Files'.

Then I went to this location encircled on my PC

Here, I extracted that aruco zip file I downloaded before. After extraction, you will find one new aruco folder inside that Roaming folder.

2. Another thing I did was within Pycharm I went to the Terminal inside Pycharm.

This area. My project name is 'untitled', might be different for you.

Here I executed:

pip install opencv-contrib-python

After installation, you can type python within the terminal and check if import cv2.aruco is working fine or not.

So to conclude, I dont know which one worked but I did both to be on the safer side and Voila!

PS: Kindly restart PyCharm after applying these changes.
