yep. It's a known issue. You're going to have to make the circuit fit a numpy value

You might just want to grab n-block's version. He seems to be on top of things

I've fixed the this issue, but have no authority of "pull request"
but I've tested attached code, works well.

Reason why issue happened is self.KK_circuit_fit[i].real and self.KK_circuit_fit[i].imag not aligned to array data format.

so it should be changed following
(I'm in office so not possible to upload the screen shot and code)

    #changed by Gim
        length_of_kk_circuit_fit = len(self.KK_circuit_fit[i])
        KK_circuit_fit_real = []
        KK_circuit_fit_imag = []
        for idx in range(length_of_kk_circuit_fit):
            KK_circuit_fit_real.append(self.KK_circuit_fit[i][idx+length_of_kk_circuit_fit].real)
            KK_circuit_fit_imag.append(self.KK_circuit_fit[i][idx + length_of_kk_circuit_fit].imag)

        KK_circuit_fit_real = np.array(KK_circuit_fit_real)
        KK_circuit_fit_imag = np.array(KK_circuit_fit_imag)
        self.KK_rr_re.append(residual_real(re=self.df[i].re, fit_re=KK_circuit_fit_real, fit_im=-KK_circuit_fit_imag))#relative residuals for the real part
        self.KK_rr_im.append(residual_imag(im=self.df[i].im, fit_re=KK_circuit_fit_real, fit_im=-KK_circuit_fit_imag)) #relative residuals for the imag part
        # changed by Gim

        #self.KK_rr_re.append(residual_real(re=self.df[i].re, fit_re=self.KK_circuit_fit[i].real, fit_im=-self.KK_circuit_fit[i].imag)) #relative residuals for the real part
        #self.KK_rr_im.append(residual_imag(im=self.df[i].im, fit_re=self.KK_circuit_fit[i].real, fit_im=-self.KK_circuit_fit[i].imag)) #relative residuals for the imag part
