ValueError: RAGatouille is not installed. Please install it with `pip install ragatouille`.

I'm trying out RAGatouilleRetrieverPack from the llama_pack.

```python
from llama_index.core.llama_pack import download_llama_pack
from llama_index.llms.openai import OpenAI

RAGatouilleRetrieverPack = download_llama_pack(
"RAGatouilleRetrieverPack", "./ragatouille_pack"
)

llm = OpenAI(model="gpt-3.5-turbo", temperature=0)

ragatouille_pack = RAGatouilleRetrieverPack(
all_documents,
llm=llm,
index_name="my_index",
top_k=5
)
```

For some reason, it says that RAGatouille is not installed, when in reality I have installed it. Here's my `requirements.txt` (quite length)

I hope to try out ColBERTv2. Any help is appreciated.

Start by reproducing the RAGatouilleRetrieverPack example with RAGatouille 0.0.8 and the provided requirements.txt. Inspect how the pack checks for the RAGatouille dependency and compare that environment with the interpreter running the example. Done means the installed package is recognized and the pack can proceed past this ValueError.
