Urgent Help Needed, Need to install on Headless OpenCv on Jetson Nano

I am trying to download opencv and albumentations. To download albumentations and imguag, you need open cv headless, open cv contrib.

I followed the steps in this link: Imgaug on Jetson Nano.

However this does not. I downgraded pip to version 19, changed setup.py, and it continues to return errors.
I also tried to the same process with pip version 20, and it returns even more errors.

I have one jetson nano
