Create ML Training Error - Activity Classifier

Hi,

I have made several ML models previously with more than one feature column, always worked great.

But now in a new project I have a set of data (with multiple csv files) with a single feature column.

Create ML loads the data well, but when I try to train the model I keep getting this error message:

"Feature column Y is empty on row 0 of input data table"

Y is the name of the column, that's correct. But I have no row 0.

I tried to convert CSV files to JSON, didn't work, I keep getting the same error.

I would appreciate any help 🙂

Best Regards,
Joel Balagué
