Error encountered on google colab, same code is working good on windows

Code :

for i in x_train: 
    for j in y_train:
        while i[:5]==j[:5]:
            raw= mne.io.read_raw_edf(i,stim_channel='auto',preload=True)
            annot_train = mne.read_annotations(j)
            raw.set_annotations(annot_train, emit_warning=True)
            break

Error :
