llm_transformer.convert_to_graph_documents TypeError: list indices must be integers or slices, not str

Open VJJJJJJ1 opened this issue 7 months ago • 15 comments

Checked other resources

  • [X] I added a very descriptive title to this issue.
  • [X] I searched the LangChain documentation with the integrated search.
  • [X] I used the GitHub search to find a similar question and didn't find it.
  • [X] I am sure that this is a bug in LangChain rather than my code.
  • [X] The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).

Example Code

    loader = TextLoader(file_path)
    # loader = Docx2txtLoader(file_path)
    documents = loader.load() # + docx_documents
    print("texts doc: =============================")
    print(type(documents))
    text_splitter = RecursiveCharacterTextSplitter(
        chunk_size=800, chunk_overlap=200)
    # text_splitter = TokenTextSplitter(chunk_size=512, chunk_overlap=24)
    texts = text_splitter.split_documents(documents)
raph = Neo4jGraph()

    llm_transformer = LLMGraphTransformer(llm=model)
    print("===================load llm_transformer!=========================")

    graph_documents = llm_transformer.convert_to_graph_documents(texts)
