It is obvious that when you have an epoched .set file exported from eeglab with no events in it, mne fails to load it with read_epochs_eeglab or read_raw_eeglab. When trying to open with read_epochs_eeglab, it throws the error:

IndexError: list index out of range

I also tried to open it by setting events parameter to empty array and None but it still failed. And when trying to open with read_raw_eeglab, it throws the error:

TypeError: The number of trials is 43. It must be 1 for raw files. Please use mne.io.read_epochs_eeglab if the .set file contains epochs.

I really need to open the epoched set file with no events in it.
