Description

It seems turicreate doesn't like sqlalchemy connections. Fair enough. I can connect to it using pandas instead and then create an SFrame from it.

Turns out, though, that in pandas string types are represented under the umbrella of dtype(O). And turicreate doesn't recognise these as strings.

pandas and sqlalchemy play really nice with each other, and I would wage there's a lot of people in the community who use these in conjunction to simplify fast prototyping. Is this problem something you would like to look into?
