1 year ago We require a specific version of haystack https://github.com/IntelLabs/fastRAG/blob/e5dea518e3ef243965016bf2ebb63b2789d1845c/setup.cfg#L5 as newer versions remove the Seq2SeqGenerator class. In order to run fastRAG, there's no need to manually install Haystack, much less so installing it by cloning it locally (unless you want to edit and modify Haystack source code), as it's not the recommended way of installing it, see https://github.com/deepset-ai/haystack#-installation.
Problem Hi, I am trying to reproduce the knowledge graph example you provided here
but I am getting the following error:
File "xxx/haystack1.py", line 6, in
from fastrag.readers import FiDReader
File "xxx/lib/python3.8/site-packages/fastrag/init.py", line 4, in

from haystack.nodes import Seq2SeqGenerator
ImportError: cannot import name 'Seq2SeqGenerator' from 'haystack.nodes' (xxx/haystack/haystack/nodes/init.py)

Steps to reproduce git clone https://github.com/deepset-ai/haystack.git cd haystack pip install --upgrade pip pip install -e '.[all-gpu]'
pip install git+https://github.com/IntelLabs/fastRAG.git
