bug

Hi @DaniloOPAvanade sorry you ran into this issue and thanks for reporting. We've found two reasons why customers hit this...

  1. Are you trying to do value prediction on a string? If you chose "Value Prediction" (regression) as the scenario, the Label to predict must be of type Single. If the Column4 is a number check it's Data Type on the Data Tab -> Advanced Data Options window. If you can share your data with me I'd be happy to look at it.
  2. We have an older bug in this space. Updating to the latest version has fixed it for many customers.

Any luck with the above suggestion?

@DaniloOPAvanade, I'm closing this issue due to lack of activity. If you're still seeing this problem, please update to the latest version https://marketplace.visualstudio.com/items?itemName=MLNET.07.

If that doesn't fix the problem, please ensure that you're label column is of type "single". You can change this in the Data Tab -> Advanced data options.

If you're still having problems feel free to re-open and @ mention me. Thank you for reporting!
