Running the IMDB Scripts

I am trying to run the script from the IMDB_Scripts Folder. I have tokenzied twitter postings and created a language model on this data.
Afterwards I have fine_tuned on the same twitter postings and created a classifier.

When I run the script it prints a confusion matrix and a fire trace:

Accuracy = 0.85645625 Confusion Matrix =
[[68939 11107]
[11860 68094]]

Fire trace:
1. Initial component
2. Called routine "eval_clas" (
3. ('Could not consume arg:', '--clas--id')

Why can’t i consume the arg? Does something go wrong?
