Hi @cpmurray 

Thank you for your patience. After further review, the lab environment is working as intended. I was able to replicate this issue by using "Serverless".

Please note that the notebook instructions state: “REQUIRED – SELECT CLASSIC COMPUTE.” This lab environment provides a dedicated cluster for that purpose.

Try to attach your notebook with the "labuser[number]" cluster instead of Serverless and let us know.

Thank you! If this resolves your issue we appreciate to accept it as solution.
