From the looks of Traceback, it is not SQL client issue. It is an error of missing library attr.

ModuleNotFoundError: No module named 'attr'

you can refer to this link to resolve the issue. ImportError: No module named attr

It says attr module not found Try to install the module:

     pip install attr

Then run again.
