when I using UnstructuredElementNodeParser to parse some html files, I got this error:Att

Please stand by @Ar1s as I search the knowledge base. I normally take about 20 seconds or so. :wave:

Hmm, I don't know enough to give you a confident answer yet. The error you're encountering typically occurs when you're trying to call a method on a None object. In the context of UnstructuredElementNodeParser, it might be related to the parsing process of the HTML files.

However, without more specific information about your code and the context in which this error is occurring, it's hard to provide a definitive solution.

I recommend checking the HTML files you're trying to parse to ensure they are well-formed and don't contain any elements that might cause the parser to return None. Also, make sure you have installed the necessary packages (unstructured and lxml) as mentioned in the UnstructuredElementNodeParser documentation ().

If the problem persists, you might want to refer to the LlamaIndex documentation () or seek help from the LlamaIndex community or support.

@kapa.ai this is my code, can you check it for me :
Settings.llm = OpenAI(model='gpt-3.5-turbo')
reader = FlatReader()
files = reader.load_data(Path(r'./R_LOS.html'))
parser = UnstructuredElementNodeParser()
nodes = parser.get_nodes_from_documents(files)

Let me check the knowledge base for you. One moment! :books:

----------------------
Your code seems to be correct according to the examples provided in the knowledge sources. However, the error you're encountering typically happens when the parser is trying to find an element in a None object. This could be due to the HTML file not being loaded correctly or the file might not be well-formed.

Here are a few things you could check:

1. Ensure the file ./R_LOS.html exists in the correct directory and is accessible.

1. Check if the file is a well-formed HTML file. You can use online HTML validators for this.

1. Make sure you have installed all the necessary packages and dependencies.

If the problem persists, it might be a good idea to debug your code step by step to see where exactly the None object is coming from.

Here is your code for reference:

this usually means one of your nodes has no text 🤔
