hard📝 Application Q9 of 15

LangChain - Evaluation and Testing

ACreate a new evaluator class implementing the evaluation interface and pass it to the pipeline

BModify the EvaluationPipeline source code directly

CUse a different pipeline class that supports custom logic automatically

DAdd custom logic inside the inputs list before passing to pipeline

Step-by-Step Solution

Solution:

Step 1: Understand extensibility via evaluators
Langchain allows custom evaluation by implementing evaluator classes.
Step 2: Pass custom evaluator to pipeline
Pipeline uses the evaluator interface to run custom logic without modifying core code.
Final Answer:
Create a new evaluator class implementing the evaluation interface and pass it to the pipeline -> Option A
