Python. Same modules in multiple microservices?

Question

Python

Need advice!
There is a large library, which is a complex tree of directories with various Python modules.
All these modules are used simultaneously in several (7) microservices, and after changing one file, you have to change it manually everywhere. I don’t have time to follow everything, all sorts of stupid bugs follow from this.
How it is possible to realize the centralized change of files of this library?
I thought about pip - a package, but, unfortunately, I have not come across it before and I can’t figure out how to implement it with such a large tree. Well, and I will be very grateful for help with building a pip package, if possible, of course)

Answer 1

Of course, a artisanal method, but I just raised the Nginx web server, and in python, the initialization module at startup calls the server for updates and downloads all the files. Surely it is also possible to form a pip package with a download link from nginx
