I've been trying to get this dataset http://archive.ics.uci.edu/ml/datasets/Communities+and+Crime+Unnormalized
into Weka and no luck at all. I converted it to CSV and then loaded it into Weka and then tried to convert it to ARFF but still giving me the error "attribute names are not unique"
.
Also, do I have to spread the training dataset from testing dataset or keep them together?
You can also use the ArffViewer (Tools -> ArffViewer or Ctrl+A). Then open your CSV file.
Next go to File -> Save as... and select Arff data files (should be selected by default).
Note that your fields must be separated with a comma and not a semicolon.
