3 months ago randn is not in numpy but in numpy.random. The solution is already in pull requests but not merged.. A clean fix would be to replace your second line by from numpy.random import randn
When using : pip3 install roboticstoolbox-python and importing roboticstoolbox as rtb, it throws an error related to scipy. randn cannot be directly imported from Scipy. So the modifications in EKF file is required. Old EKF file: from scipy import integrate, randn Change to new EKF file:: from scipy import integrate [remove the randn] from numpy import* [add this line and save]
Then the error is gone and everything works fine.
