error importing carculator_bus

[mfastudillo]

Hi

When I try to import carculator_bus I get an error related to deprecated function in inspect (getargspec). This is part of the atmos package that is used somewhere. Inspect deprecated getargspec a long time ago.

This problem may be simply because the version in pip is quite an old one ? https://pypi.org/project/carculator-bus/
