raw_train = mne.io.read_raw_edf('C:/Users/Admin/Downloads/wesley_annot2022.03.11_12.18.26.edf', stim_channel=None)
annot_train = mne.read_annotations(raw_train)

raw_train.set_annotations(annot_train, emit_warning=False)

raw_train.plot(start=60, duration=60,
               scalings=dict(eeg=1e-4, resp=1e3, eog=1e-4, emg=1e-7,
                             misc=1e-1))

while running this code I get the following error:

ValueError: invalid literal for int() with base 10: ''

Kindly help me to fix this error.

It would really help readers if you formatted your code in your question correctly (I’ve done this for you now).

Regarding the issue, mne.read_annotations() takes the filename as the first input argument, but you are trying to load that file with mne.io.read_raw_edf(). Can you try to run

annot_train = mne.read_annotations('C:/Users/Admin/Downloads/wesley_annot2022.03.11_12.18.26.edf')

to see if this fixes the problem?

Thank you @cbrnr for your support. I will structure my code from now on. I was now able to read the annotations. thank you so much.
