this error occurs when you use a pickle file generated on a different CPU architecture which supports avx2. Try to generate your own pickle file

Hi siddhantdante I ran into the same error, how can I generate my own pickle file, given I am in a windows OS? , and based on what should i generate it?

Had the same problem on a mini M2. Fixed in by running "python ingest_data.py" to create a new pickle file.
This step is covered in the blog post https://blog.langchain.dev/tutorial-chatgpt-over-your-data/ which I failed to read carefully enough.

Had the same issue on Win11 home ed. 22h2. Followed what @fowlert did to fix it.
