Hey There, I dont know if this is a bug on Module 2 - The vector embeding code example is calling the refresher python lab

Hey @eolivera, I believe this refresher page is not in module 2 but in module 1 (ungraded lab 1) indeed. I’ve checked module 2’s ungraded lab and the content looks relevant in the git repo: [https://github.com/https-deeplearning-ai/rag/blob/master/Module2/ungraded\_labs/ungraded\_lab\_1/C1M2\_Ungraded\_Lab\_1.ipynb](https://github.com/https-deeplearning-ai/rag/blob/master/Module2/ungraded_labs/ungraded_lab_1/C1M2_Ungraded_Lab_1.ipynb)

I see only alpha testing version of the course at Coursera which didn’t include this section yet; can someone else testing the RAG course in beta phase confirm the same issue?

Hello @ondrous I am taking the course on deeplearning.ai, I dont know if anyone else has the same bug. I keep seeing the same error the lab from the module 1(C1M1\_Ungraded\_Lab\_1) in the module 2
