for building and evaluating RAG pipelines, previously the llama_index was used. now i changes in my llama_index.core and also i used from llama_index.core.settings import Settings instead of service context but my python stuck on this issue. " ModuleNotFoundError: No module named 'regex._regex'" can any one help in this regard?
This to me seems like your python wasn't installed correctly. You can try pip install regex --ignore-installed -- but tbh you might have to reinstall python
