Hello, I’m working on visualizing EEG data from a Muse2 headset. I’ve followed the pre-processing code given in the docs and this is what it looks like:

        data = pd.read_csv(f"{eeg_csv_filename}")
        channel_names = data.columns[1:]
        eeg_data = data[channel_names].values.T
        info = mne.create_info(channel_names.tolist(), sfreq=256, ch_types='eeg')
        raw = mne.io.RawArray(eeg_data, info)

        ica = mne.preprocessing.ICA(n_components=4, random_state=97, max_iter=800)
        ica.fit(raw)
        ica.plot_properties(raw, picks=[0, 1 , 2 ,3])

This gives me the following error:
RuntimeError: No digitization points found.
I can’t figure out how to fix this, any pointers would be appreciated.
MNE version: 1.4.0

ica.plot_properties() requires electrode locations, so you need to assign a montage for that to work.
