説明

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?

調査方針
Investigate how turicreate's SFrame constructor maps pandas DataFrame dtypes. Look at the Python bindings for SFrame construction, likely in src/python/turicreate/data structures/sframe.py or similar. Identify if pandas object dtype is being coerced to a different type and modify the conversion logic to treat it as a string. Review the comments on issue #92 for any additional context or suggested approaches.
