Hi everyone.
The best solution to solve this and other issues, is downgrading to version 5.7.0.
Jupyter changed a lot of things, and so did the other modules, probably making something along the way conflict.
Update: the %matplotlib notebook magic does not work anymore for ChipWhisperer notebooks, instead Python’s chipwhisperer library included and installed during initial setup can be used to plot interactive graphs.
Example:
import chipwhisperer as cw
cw.plot([1, 2, 2, 4, 5])
Thanks to NewAE staff for being much cooperative and patient.
