Question for Unit 9.1

I installed NGSOVE from pip with python3.9. Everything works fine. However, when I’d like to run unit 9.1

it shows error as below for code block [1]. I can run all the other codes correctly. Could you please help me with including the path into “CppExtension.ipynb”? Thank you!

importing NGSolve-6.2.2301
