Port my python program to Raspberry pi seamlessly

[Hassibayub]

I'm working on the IRIS recognition system and it is almost complete now.
Now the pain is to port this program from my laptop (working in conda environment) to raspberry pi 3b+.

I know raspberry pi does not support every package and it is hard to install some of the packages, tons of errors and dependencies compatibility issues (ie: Opencv is a pain for a naive Linux user)

I'm looking for a seamless solution to port my program with minimalistic setup somehow (incl. OpenCV)

I've seen docker and spent 2 days on it and didn't get it how it's useful for my case.
