Thank you for the logs. I've confirmed that this is a bug of the package requirement in Tacker. The attribute 'Computed' in sqlalchemy is supported from 1.3.11 [1] but our requirement shows it to be 1.3.0 [2]. I guess your sqlalchemy is lower version than 1.3.11. I'll report this as a new bug in Tacker.

You can try to upgrade your sqlalchemy to be equal to or later than 1.3.11 if possible (you may find another requirement issue). Or as I mentioned before, you can try to manually upgrade the DB with SQL I listed above.
