Hi Yanbo,I think it was happening because some of the rows did not have all the

Can you supply the detail code and data you used.From the log, it looks like
can not find the bin for specific feature.The bin for continuous feature is a
unit that covers a specific range of the feature.

Hi All,
I am using the decision tree algorithm and I get the following error. Any help
would be great!
