Cannot install Rasa X - sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) no such column: True


I looked at this thread which is reporting the same error but it’s not clear how it was fixed. So I am raising it again here to get some help …

I am running the following versions:

rasa 2.8.1 rasa-sdk 2.8.1 rasa-x 0.42.0

I am using Ubuntu 18.04 and running Python 3.6.9.

I have tried deleting the events and rasa db files (which previously worked for me) via this thread but I’m afraid it still doesn’t work. I had the same error with rasa 2.7.1 and corresponding SDK and rasa-x versions from the compatibility matrix.

Can anybody help?


@pomegran Downgrade to rasa-x==0.39.3

pip install rasa-x==0.39.3 --extra-index-url

Somre errors:

ImportError: cannot import name ‘RowProxy’ from ‘sqlalchemy.engine’ try running pip install SQLAlchemy==1.3.22 should fix it.)

And, if you get an error not being able to import yaml then run pip install pyyaml.

Good Luck!

That’s fabulous, thank you!

In the interests of completeness, I returned to my original Rasa 2.7.1 and Rasa-sdk 2.7.0. Installed Rasa X 0.39.3 and then needed to run:

pip install SQLAlchemy==1.3.22

All worked!

Are there problems with Rasa X post 0.39 then?

Thanks for your help! Much appreciated.

@pomegran Congratulations Mark :handshake: Party :clinking_glasses:. I guess its a backend issue in Rasa, hope they will solve it soon.
