Thanks for the additional info!
To create a feature group in the online feature store, a schema is required, e.g. you have to specify the features and their types. The error is not very informative, I have to admit.
Creating an offline-only feature group without schema should be possible.
Additionally, there seems to be a bug, and the offline part of the feature group gets created, whereas the online part fails afterwards, but the whole operation should fail from the start.
I created a Ticket for that on our side to fix this and improve the error message.
So I recommend you to clean up this half created feature group. You can do so by going to the “Data Sets” browser service, go to the
Featurestore.db directory and delete the directory of the feature group you tried to create, which should be called
With respect to your second problem, with version 2.0 of Hopsworks we started to deprecate the
hops.featurestore module in favour of an all new client called
HSFS which should be much more intuitive to use and comes with much more functionality, you can find documentation about it here: https://docs.hopsworks.ai/.
Are you trying to connect from you local Python environment on your machine or from a Jupyter Notebook within Hopsworks?
