The solution is pretty easy. I made the mistake, that I defined the summit frequencies fs as well as the constant phase elements Q. This resulted in an overdetermined system....

One solution is to change the 4701 entry from (original) `ax.plot(self.circuit_fit[i].real, -self.circuit_fit[i].imag, lw=0, marker='o', ms=8, mec='r', mew=1, mfc='none', label='')` to (my solution) `ax.plot(self.circuit_fit[i].values.real, -self.circuit_fit[i].values.imag, lw=0, marker='o', ms=8, mec='r', mew=1, mfc='none',...
