Hi,

First of all thank you for developing a very useful library with a good documentation guide.
I am using this library for a EEG classification and was really interested in trying the online code which is given.
I am getting an error as shown in below image when I run the code.
Could you please let me know what's the issue

Thank you

I am running the code for dataset 2 from wyrm/examples/BCI Competition 3, Data Set 2 (P300 Speller).ipynb. during running of last step I am facing the error "TypeError: '<' not supported between instances of 'tuple' and 'list'".

TypeError Traceback (most recent call last)

Hi!
I run code python wyrm/test/test_select_channels.py and I get an error
Thanks for everything.
