Create ML doesn't read csv

I'm bad at English...

I'm using create ML. I'm using X code. The csv file cannot be read. The same thing happens with core ML API.

The structure of csv is as follows.

** text,labelA,labelB,labelC,labelD

hello,2,3,4,5

good,3,4,5,6 **

I tried some. I don't think the structure is wrong...

I think it's a setting problem.

Please help me.
