Do not call multiprocessing module in frozen binaries

[vasole]

Calls to multiprocessing fail when using PyInstaller frozen applications

How about instead of doing this

def retry_in_subprocess(
   ...
):
   
    import multiprocessing
    def decorator(method):
        @wraps(method)
        def wrapper(*args, **kw):
             ...

        return wrapper

    return decorator

do this

def retry_in_subprocess(
   ...
):
   
    def decorator(method):
        @wraps(method)
        def wrapper(*args, **kw):
             import multiprocessing
             ...

        return wrapper

    return decorator

Ah ok, multiprocessing will not work at all, so yes your solution is better.
