problems printing out results and plotting from fooof group object

[maboudewyn]

Hello,
I am working on fitting a group of power spectra using the tutorial here: https://fooof-tools.github.io/fooof/auto_tutorials/plot_06-FOOOFGroup.html

I was able to initialize a fooof group object and fit the group of spectra using the .fit() method. However, when I try to plot a summary of the model using fg.plot(), only the aperiodic fit and error plots populate; the center frequencies portion of the plot remains empty and the console returns the following error:

Traceback (most recent call last):

out = np.array([np.insert(getattr(data, name), 3, index, axis=1)
ValueError: setting an array element with a sequence. The requested array has an inhomogeneous shape after 1 dimensions. The detected shape was (25,) + inhomogeneous part.

This same error comes up when I try the following with the fooof group object:
fooof.objs.average_fg()
get_band_peak_fg()
fg.print_results()

Interestingly, the following DOES work:
print(fg.group_results[0:])

• the below works when any of the 25 fits = ind
  fm = fg.get_fooof(ind=4, regenerate=True)
  fm.plot()

I have also checked the organization of the data:
print(freqs.shape)
print(spectra.shape)
Out:
(204,)
(25, 204)

I am sure I am doing something wrong, but I'm not sure what!

Thanks

Hey @maboudewyn - I think this is the same issue as #313, if you check and make sure your versions of fooof and numpy are up date, that should fix it!

That worked, thank you!
