Error: "local variable 'chunk_id' referenced before assignment

[xueshun-6estates]

When running the convert_parquet_to_png.py script, an error occurs at the process_guichat() function. The error indicates that the chunk_id variable inside the write_images_version2 function is not initialized. I wonder if this is a bug or if there are any underlying reasons for this issue.

Thanks for your question, I have corrected this error. You can use the new code. https://github.com/yiye3/GUICourse/blob/ecda29e5f4e6cdc6a7d4531fc7cfb8197e95bcfc/data_preprocess/convert_parquet_to_png.py#L61
