TypeError: unhashable type: 'slice'

It is not running on regression problem, how can I run it on regression model?

my dataset is ptb ecg database. you can check it on https://www.physionet.org/physiobank/database/ptbdb/

firstly you read the description. I want to know how to convert these twelve columns (i, ii, iii, avr, avl, avf, v1, v2, v3, v4, v5, v6) into features for...

this is how my one data column which I (i) as I mentioned above looks like

thanks @DominiqueMakowski it is really useful, but tell me ecg_preprocess() and bio_process() works alike in my case?

as I have already mentioned you that I am using dataset of PTB ecg dataset, and your library also inculcates it. But ecg_preprocess() also fails on some signals giving error...

If I only process LEAD 1 (i in my data), then would it give features which ('T_Waves', 'Cardiac_Cycles', 'P_Waves', 'Q_Waves', 'HRV', 'R_Peaks') helps me in classification of heart disease class.
