MEKA is the open source machine learning framework. I have a created a *.arff file for text contents for solving the multi-label classification. But I couldn't execute the data. I am getting the following error when I run the Binary relevance based Naive Bayes method for my *.arff file.

Evaluation failed (CV):
java.lang.ArrayIndexOutOfBoundsException:1

I have also compared the data format with the existing datasets like imdb.arff, bibtext.arff. The data format looks as below:

@relation 'MovieR: -C 0'
@attribute Ease {0,1}
@attribute Satis {0,1}
@attribute Effect {0,1}
@attribute 000 numeric
@attribute 1 numeric
@attribute 10 numeric
@attribute 1000 numeric

you must specify number of categories in this line @relation 'MovieR: -C 0'

for example: if it is the first 2 attributes then it will be: @relation 'MovieR: -C 2'

if it is the last 2 attributes, then it will be: @relation 'MovieR: -C -2'
