Hi All,
I used the 20NewsGroup model to train my data. However, while trying to test
the classifier (test data is same as train data just for simplicity sake
now), I get the following error. Any ideas?
dipti@dipti-laptop:~$ mahout/trunk/bin/mahout testclassifier -m
ruralsearch/bayes-model/ -d ruralsearch/test-input/ -type bayes -ng 1
