Auto Model Throws Error immediately with this data. What is wrong with it?

pblack476

So there seems to be something that AM does not like about this data but I cannot figure out what it is. everything seems to be in order but every learner throws out an error and when I look at the log for any one of them the answer is the same:

The attribute Close)_2 was already present in the example set.

Appreciate the help!

Hi @pblack476,

Yes, in deed, AutoModel does not accept actually the attribute names with brackets "(".
To my knowledge, this bug is already known from the RM staff...

The work around is to replace the brackets by an underscore (for example).
To do that , you can use the Rename by replacing operator

In attached file, you can find a process renaming your dataset.

Hope this helps,

Regards,

Lionel
