Best way to import a python module into the root of a package hierarchy from another module in one package

Question

I am writing a package P. There is a module m0 in the root of P. Somewhere inside P there are modules m1, m2, ... that need to be imported from m0

Of course, I can write in each of these modules:

from P.m0 import ...

However, if I change the name P, I need to review all the places and rewrite such statements.

I could also use relative imports, but if I translate the module at a different level in the package hierarchy, I have to fix the number of points.

There are other reasons, but on the bottom line, I really want to say that importing from the m0 module, which is at the root of my package, what is the best way to express this?
