Hi,

I setup a virtual environment (tried both conda and venv), activated it and installed pip requirements per course instruction. When running the notebooks for the Duet Basics demo I get an error at the first statement in both notebooks while loading the pysyft library (same error). I am running on macOS 11.1 Big Sur.
