cannot import name 'context_precision' from 'ragas.metrics'

[dividor]

[X ] I have checked the documentation and related resources and couldn't resolve my bug.

Describe the bug
I am trying to follow this documentation, but it doesn't work because context_precision seems to be missing.

Ragas version: ragas-0.1.14
Python version: 3.11.4

Code to Reproduce
The code from Ragas' documentation ...

from ragas.metrics import (
    answer_relevancy,
    faithfulness,
    context_recall,
    context_precision,
)

Error trace

Expected behavior
The documented code should work.

Additional context
RAGAs is great, thanks!

Hey @dividor! 👋 I'm here to help you out with any bugs or questions you have. I'm a bot that can assist with problem-solving and answering queries while you wait for a human maintainer.

The ImportError occurs because context_precision is not defined as a module-level variable in ragas.metrics. Instead, it is defined within src/ragas/metrics/_context_precision.py.

To resolve this issue, you can import context_precision directly from ragas.metrics._context_precision:

from ragas.metrics._context_precision import context_precision

Alternatively, you can import it directly from ragas.metrics as it is included in the __all__ list in the src/ragas/metrics/__init__.py file:

from ragas.metrics import context_precision

This should resolve the ImportError you are encountering ^[1][2].
