Ok, thanks for that test. What it means is that the issue is not related to IDE, but rather with the package or interpreter.
Unfortunately I can't give you a definitive solution for now. You can also try asking for help on resources like StackOverlow or apriltag github page. Let's see if someone else here ran into a similar issue.
Hi, please try to reproduce the issue in your system terminal (outside of PyCharm):
1. cd to your project root
2. activate virtualenv with `cv/scripts/activate.bat`
3. install with `pip install apriltag`
Will the issue reproduce?
Dear Andrey,
Kindly find the attached screenshot of the cmd after following your request.
Thank you in advance!
