    Hello @mrzh

    Are you getting an error or just you are unable to see a decision tree? Did you try the decision tree by removing "Pruning option"?

    You can set a breakpoint before decision tree and observe the data going into it to see if all the 748 attributes are going into it with 726 samples or not.

    Hope this helps.
