@GreameLee have you installed the toolbox? seems that the data is missing, but this should only happens if you did not pip install . as the instructions suggest. Or did you do that, but still get this error??

[GreameLee]

@AnderBiguri Yes, I do all the instructions step by step and successfully did it and tried several times but still got this error. And when I go to the sample_loader.py file and put test_data as an absolute path of head.mat, it can run now. I guess there is a problem with the relative path.

Thanks! for your own, that change should suffice to keep you going. I will investigate soon to see if I can find a fix that is general.
