Issue: You seem to be using the pipelines sequentially on GPU. In order to maximize efficiency please use a dataset
Root cause: External Dependency Breakage

I got the error below while running the generator.generate_with_langchain_docs.  How to set it up to use GPUs?

```python
generator.generate_with_langchain_docs(docs, test_size=10, distributions={simple: 0.5, reasoning: 0.25, multi_context: 0.25})
```

hey @JPonsa sorry about this

but what models are you using? by default we use LLMs and Embeddings which are openai - if seems like you have some transformers models

hi @jjmachan using vLLM. Now I don't remember the LLM, Either mistral7b or llama2-7b

did you get this fixed @JPonsa ?

but I'll test it with vLLM shortly and write a testcase for that too

@jjmachan , not sure, probably, I cannot test due to https://github.com/explodinggradients/ragas/issues/871

ohh understood, I'll prioritize that one first then, get that sorted for u 🙂
