I am receiving syntax errors "Expected valid syntax." for all CLI tools that are based off n-grams and which require the user to supply the n parameter. I think there is an error somewhere in how the opts is parsing the integer. The following are not working for me:
dicesorensenmetric
jaccardmetric
ngrammetric
overlapmetric
Commenting out the the opts and hardcoding the n value resolves the issue.
