No module named 'ragas.langchain'

I get a error when run this import:

    from ragas.langchain import RagasEvaluatorChain

ModuleNotFoundError Traceback (most recent call last) Cell In[5], line 1 ----> 1 from ragas.langchain import RagasEvaluatorChain

ModuleNotFoundError: No module named 'ragas.langchain'

I have the version 0.1.0 of RAGAS. I tried with other older versions but I get the same error.

According to this issue: https://github.com/explodinggradients/ragas/issues/571

ragas 0.1 does not support it yet:

ragas 0.1 does not yet have this feature. We are working on it, for now you have two options

Use ragas natively w/o the chain, in this way, you get all the new capabilities of 0.1 version reinstall and use 0.0.22

You can downgrade it to ragas 0.0.11, just make sure to remove context_precision as it's not supported at this version

I fixed it by installing ragas==0.0.11. LangChain article was written on August 23, 2023, while Ragas v0.0.11 was released the day after that.

If you use v0.0.11 also make sure to remove context_precision as not yet supported back then.

You can keep following that issue to check when this is going to be solved
