Difference Between Python and MATLAB Spectrograms

I am comparing the MATLAB and Ptyhon spectrogram output stft and Sxx. The values of stft and Sxx differ by orders of magnitude and are not linearly related. Why is this?

MATLAB

[stft,f,t] = spectrogram(x,nWind,nOver,[],sRate);

Python

f, t, Sxx = scipy.signal.spectrogram(x, fs=sRate, nperseg=nWind, noverlap=nOver, nfft=256, mode='complex')

Was this ever resolved? I'm having the same issue and I'm wondering why they are different and what else I should do to get the same results between two programs. I really don't want to convert my Matlab to Python at this time. I'm using someone else's Python code.
