Fix(evaluator): Fixed evaluator commands

[Kaushl2208]

Description

The Evaluator commands are set for both two parameters i.e agent_name and similarity but some agents run without similarity type also. This needed an easy fix in the evaluator.py file.

Changes

• The default similarity type is changed from "CosineSim" to " ".
• A simple if-else statement is written for the new condition in both the Agent types.

Testing and verifying

You can test and verify by using the commands: python evaluator.py -a tfidf For tfidf python evaluator.py -a Ngram for Ngram
