Bugs in Tutorial

[etherealsunshine]

While running the tutorial I caught an AttributeError stating : 'NoneType' object has no attribute 'squeeze' while running the second code snippet.

PDC = analyses.compute_conn_mvar(no_ICA_complex_signal, 
                                 mvar_params={"mvar_order": 2, "fitting_method":"default", "delta": 0},
                                 ica_params={"method": "infomax_extended", "random_state": None},
                                 measure_params={"name": "pdc", "n_fft": 512}
                                 )

no_ICA_result_inter = []
for i in [0, 1]:
    PDC_q = PDC.squeeze()
    if i == 0 :
        mvar_spectrum =  PDC_q[n_ch:n_ch*2, 0:n_ch, :]
    else:
        mvar_spectrum =  PDC_q[0:n_ch, n_ch:n_ch*2, :]   
    PDC_fmax = np.zeros((n_ch, n_ch), dtype=PDC.dtype)
    for j in range(0, n_ch):
        for k in range(0, n_ch):
            PDC_fmax[j, k] = np.amax(mvar_spectrum[j,k,:])
    mvar_values_inter = PDC_fmax
    mvar_values_inter -= np.diag(np.diag(mvar_values_inter))
    # computing Cohens'D for further analyses for example
    mvar_C_inter = (mvar_values_inter -
               np.mean(mvar_values_inter[:])) / np.std(mvar_values_inter[:])
    # can also sample CSD values directly for statistical analyses
    no_ICA_result_inter.append(mvar_C_inter)

This error will come up if you do not answer the input when the code asks a question(and just press enter)

Meet the same problem. And when I try to print PDC, it seems that the PDC is None type, but the no_ICA_complex_signal is fine. Did you solve the problems?

Hey there,

Could you check if you answered the input prompt as shown below? If you answer it, the code should work.

Also if you're facing issues with numpy bool, in the latest versions it's deprecated, so you'll have to downgrade

Hi! I tried to run the code, and this is what I answered:[image: image.png] And it is running [image: image.png] , but afer that we still get the error message.[image: image.png] And if you print(PDC), it will show none. [image: image.png] Also this is what I get after I tried to uninstall numpy 1.24.3 and install numpy 1.24.1. Sorry to interrupt you. Hope you have a nice day!
