I am getting the following error:
TypeError: int TMinuit::Migrad() => TypeError: callable was deleted
import ROOT gMinuit = ROOT.TMinuit(10) # setup the function, etc... gMinuit.Migrad()
This is with Root 6.22, and worked fine with Root 6.18 and previously for many years.
_ROOT Version: 6.22
_Platform: Mac (MacPorts)
Compiler: Not Provided
