Error when dealing with method load_summarize_chain

[ilyasbendev]

Hello everyone,
I'm trying to summarize text after splitting it
This is the code that i wrote :

from langchain.chains.summarize import load_summarize_chain
from langchain.text_splitter import RecursiveCharacterTextSplitter
from langchain.llms.openai import OpenAI

# split text into texts
char_text_splitter = RecursiveCharacterTextSplitter(chunk_size=3000, chunk_overlap=0)
texts = char_text_splitter.split_text(text)

# summarize using refine model
llm = OpenAI(temperature=0, openai_api_key='example_api_key')
model = load_summarize_chain(llm=llm,chain_type="refine")
model.run(texts)

I have this exception on model.run(texts)
An error occurred in model_run: 'str' object has no attribute 'page_content' .

Do anyone have any idea how to deal with that ?

Hello,

Based on the error message you're receiving, it seems like the run method of the load_summarize_chain class is expecting an object with a page_content attribute, but it's receiving a string instead.

From the context provided, it's not clear what the expected input type for the run method is, as it's not explicitly defined in the load_summarize_chain class. However, a similar issue was solved by changing the line of code from texts = text_splitter.split_documents(pages) to texts = text_splitter.create_documents(pages). You might want to try a similar approach.

Also, the split_text method of the RecursiveCharacterTextSplitter class returns a list of strings, where each string represents a chunk of the original text. If the run method is expecting an object with a page_content attribute, you might need to transform these strings into the appropriate object type before passing them to the run method.

Without more information about the run method and the load_summarize_chain class, it's hard to provide a more specific solution. If you could provide more details about these, it would be easier to help you solve this issue.

Best,
Dosu
