Hello,
I’m trying to get my ChipWhisperer running on a MacBook with the M1 processor, and am getting the error below when attempting to run Setup_Generic.ipynb. Has anyone run into this issue before? I’d really appreciate some help. “No backend available” seems to be the primary error.
Traceback (most recent call last):

if not scope.connectStatus:
NameError: name ‘scope’ is not defined
During handling of the above exception, another exception occurred:
