Dear all,
I have a problem calculating the spectrogram, I am using ppsd.plot_spectrogram() command to create it, but the terminal gives me an error: AttributeError: ‘PPSD’ object has no attribute ‘plot_spectrogram’.
I have the last version of obspy (1.0.3) and I am trying to run the source codes of this web page. https://docs.obspy.org/master/tutorial/code_snippets/probabilistic_power_spectral_density.html
Does anyone know what is the problem?
Cheers,
Juan
