[Mne_analysis] Issue with example in mne.datasets.eegbci.data_path()

[Brunner, Clemens (clemens.brunner@uni-graz.at)]

        External Email - Use Caution        

Hello!

Did you try eegbci.load_data instead of eegbci.data_path (according to the docs https://mne.tools/dev/generated/mne.datasets.eegbci.load_data.html#mne.datasets.eegbci.load_data)? What do you want to do in the first place?

Clemens
