Error running the exporter when installed from pip

[shamil]

I get error

ModuleNotFoundError: No module named 'barman_exporter.barman_exporter'; 'barman_exporter' is not a package

Once I modify the bin wrapper from:

from barman_exporter.barman_exporter import main

to

from barman_exporter import main

it works

I assume the issue is from
