Dears, I installed the latest release of Rasa x locally on macOS. once I tried to lunch the rasa using the command “Rasa x”. I faced the following issue.

```
Traceback (most recent call last):

sqlite3.OperationalError: table _alembic_tmp_conversation_event already exists

The above exception was the direct cause of the following exception:

Sorry, something went wrong (see error above). Make sure to start Rasa X with valid data and valid domain and config files. Please, also check any warnings that popped up.

Hi @mohocp, can you try deleting the `events.db` and `rasa.db` files from your directory if they already exist?

Hi @akelad , I am getting same exception "ImportError: cannot import name ‘Row’ from ‘sqlalchemy.engine’ (/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/sqlalchemy/engine/ **init**.py)

Sorry, something went wrong (see error above). Make sure to start Rasa X with valid data and valid domain and config files. Please, also check any warnings that popped up. If you need help fixing the issue visit our forum: [http://forum.rasa.com/."](http://forum.rasa.com/.%22).

I have tried deleting the events.db and rasa.db still ended up with the same error.

Please suggest. Below is the list of versions installed: pip. : 21.2.4 rasa : 2.8.6 rasa-sdk :2.8.1 rasa-x :.42.2 SQLAlchemy :1.3.22
