I was trying to do "test generation" using RAGAS framework with the help of the "https://docs.ragas.io/en/stable/concepts/testset_generation.html", I'm facing error.

Please have a look on the below error.

ragas.exceptions.ExceptionInRunner: The runner thread which was running the jobs raised an exeception. Read the traceback above to debug it. You can also pass raise_exceptions=False incase you want to show only a warning message instead.

And my code is:

loader = PyPDFLoader(" .pdf") documents = loader.load()

#used same LLM for both generator_lmm and critic_llm generator_llm = llm() critic_llm = llm() embeddings =embeddings() # used AzureOpenaiEmbeddings

generator = TestsetGenerator.from_langchain( generator_llm, critic_llm, embeddings ) distributions = { simple: 0.5, multi_context: 0.4, reasoning: 0.1 }

testset = generator.generate_with_langchain_docs(documents, 10, distributions) testset.to_pandas()

versions: openai - 1.17.0 ragas - 0.1.4/ 0.1.6

I don't think this is a Ragas issue - are you still facing this @sona-16 ?

Hi jjmachan,

I haven't tried yet on the issue. Will do it by today and update you

I am facing this same issue.

Any update? I'm facing the same message for a ragas.evaluate inside a ThreadPoolExecutor

I also have the same issue, everything worked fine for a set of 300 pdfs, and now all of a sudden the same code gives the error below:

Hi Team,

I'm still facing the same error. I doubt, is this due to huggingface LLM I'm using or due to computation power. And also, Im using google colab notebook with CPU setup to do this task.

Hi @damlitos could you please share me the code snippet, why because I have just used 2 pages of PDF, even though no proper output. As you told you may be getting an satisfactory answer for lesser # of pages.
