Hi everyone,

I am trying to load an EEGLAB dataset using mne.io.read\_raw\_eeglab(), and here are the lines:

sample\_data\_folder = 'test\_data';  
sample\_data\_raw\_file = os.path.join(sample\_data\_folder, 'test\_data.set')  
raw = mne.io.read\_raw\_eeglab(sample\_data\_raw\_file)

Then I got the error:  
TypeError: buffer is too small for requested array

I want to know why this happened and how to solve it.

Thanks for any help!

Best wishes,  
Yuri
