Data Format and Loading Error

[jmethfe]

Hi,

I am relatively new to using Scala and LIBSVM data. I grabbed the Iris dataset in the LIBSVM format from https://www.csie.ntu.edu.tw/~cjlin/libsvmtools/datasets/multiclass.html#iris

My goal is to train the algorithm with this dataset. Then I will simulate some real-time test and train data streams to observe how the tree populates and performs.

I am seeing this error when specifying my initial training dataset. The data file is saved as .dat file.

The class labels in this dataset are {1,2,3} so you need the --class-labels option:

./bin/spdt --model-path ./tmp --class-labels 1,2,3 --training-data ./iris.scale
