Dear All,
I have a dataset from Kaggle (updated). I loaded it into RapidMiner Studio and I would like to prepare a model with Auto Model function. I tried all of the opportunities but these showed the following error:

Error

Process: Support Vector Machine

The attribute A) was already present in the example set.

Could you help me to fix it?

Hi @akos_banar,

I think it is a known bug:  the root cause is the parenthesis in the attribute name.
Please remove this parenthesis in the attribute(s) name before submitting your data to AutoModel.

Hope this helps,

Regards,

Lionel
