Hey, what version of llama-index are you using? It seems like they've updated some things on their end, will work on a fix! Also related #147

@bclavie LlamaIndex maintainer here -- v0.10.x is a bit of a breaking change in terms of imports. Let me know if you need a hand with handling any migration :)

[bclavie]

Hey @logan-markewich, thanks a lot! I think all we're really using right now is the document splitter & the Document object. I could dig but I assume you're a lot more familiar than I am -- any recommendations in keeping the overall behaviour here with imports compatible with both the new version and older ones?

[logan-markewich]

Probably just need a try except

try:
  from llama_index import Document
  from llama_index.text_splitter import SentenceSplitter
except ImportError:
  from llama_index.core import Document
  from llama_index.core.text_splitter import SentenceSplitter

That should work for both v0.10.x and older versions

Thanks! Fixed in #155 (0.0.7post5)

Hi, I'm encountering the same issue with the error: ImportError: cannot import name 'Document' from 'llama_index.core' (unknown location)
Ragatouille version: 0.0.7.post5
llama-index version: 0.9.48.

Hi @RibinMTC , I too faced similar issue. Here's how i fixed it

1. uninstall ragatouille
2. reinstall with pip install git+https://github.com/bclavie/RAGatouille/
3. modify the file /path/to/venv/lib/python3.10/site-packages/ragatouille/data/preprocessors.py line 5 to from llama_index.core.schema import Document

[mallahyari]

you have to remove all the python libraries related to llamaindex (image below) and then install llamaindex again.

[logan-markewich]

Yea, either that or starting with a fresh venv is probably the ideal solution here

For me I just had to make sure setuptools is also required.
ragatouille: 0.0.7.post11
llama-index: 0.9.48

Now the error looks like this -

Plain typing.TypeAlias is not valid as type argument

Just adding it so people searching it will be able to find this thread.

Also, to get it working, I changed ( in the package ) i.e RAGatouille/blob/main/ragatouille/data/preprocessors.py -

From :
from llama_index.core import Document
from llama_index.core.text_splitter import SentenceSplitter

To:

from llama_index.legacy import Document
from llama_index.legacy.text_splitter import SentenceSplitter

Still running into the ImportError with ragatouille==0.0.8post2. Why don't we narrow down the version of llama-index to reduce the risk of pulling breaking changes? ">=0.7, <=0.10" worked great for me so far.
