Hi. I am trying to build an auto-retriever with pinecone. I am trying to use the collab notebook, it was working last week. But now I came back to it and it outputs this error UnboundLocalError: local variable 'pinecone_sparse_vector' referenced before assignment it seems like it doesn't recognize the llama_index_v2 runtime anymore which seems to do the job How can I fix this issue? Currently, the colab using python 3.10.2
