Different Outputs

[Galaont]

I was following the tutorials step by step doing nothing but copy-pasting then I encountered a weird situation. When I was on basic feature extraction, my visual outputs of zero crossing rate and spectral centroid were different than it's supposed to be in tutorial. You can see the differances below
(my output - tutorial output in order)

I'm sure I did nothing different and restarted&did it all again three times just in case, the result didn't change. Also my input hasn't been touched and I can confirm that they match in the first visuals (plt.figure part).

what may be causing this differance? thanks in advance
