when using import funtion for eeglab file:
raw = mne.io.read_raw_eeglab(‘D:\02020008rest 20150624 1711…mat.set’,
preload=True)
i received the NotImplementedError('Please use HDF reader for matlab v7.3 ’
NotImplementedError: Please use HDF reader for matlab v7.3 files, e.g. h5py
How should I do? Thanks for your help.

This error indicates that you saved your data as a v7.3 .mat file, which requires additional packages to read. If possible, save your data as a v6.5 .mat file instead (see 3. Dataset management - EEGLAB Wiki)? If that’s not an option, try installing the Pymatreader package, it should resolve your issue (just use the same command to load the data).
