I am getting this error while using MarkDownElementNodeParser , how to fix it ? 232 try

At a glance

A community member is encountering an error while using the MarkDownElementNodeParser, and is asking for help to fix it. The error message indicates an issue with pandas' file parsing, specifically an "EOF inside string" error starting at row 5. Another community member responds that the error seems to be related to pandas' file parsing, not directly to the MarkdownElementNodeParser from LlamaIndex, and it might be due to a malformed file. The community member is then provided an example of how to use the MarkdownElementNodeParser, but no definitive answer is given for the original error. The community member follows up, stating that the parser.get_nodes_from_documents(markdown_docs) is giving them the same error details as the original post.

Please stand by @Ansuman Satapathy 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 seems to be related to pandas' file parsing, not directly related to the MarkdownElementNodeParser from LlamaIndex. It might be due to a malformed file you're trying to read.

However, I can guide you on how to use MarkdownElementNodeParser based on the information I have. The MarkdownElementNodeParser in LlamaIndex is used to split a markdown document into Text Nodes and Index Nodes corresponding to embedded objects like tables. Here's an example of how to use it:

Plain Text
from llama_index.core.node_parser import MarkdownNodeParser

parser = MarkdownNodeParser()

nodes = parser.get_nodes_from_documents(markdown_docs)

(Source: LlamaIndex Documentation ())

For more specific help with your error, you might want to check the pandas documentation or relevant StackOverflow threads.

Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:

@kapa.ai parser.get_nodes_from_documents(markdown_docs) is giving me the error details posted earlier
The error was in markdown parsing
