Я пытаюсь разработать модель с использованием PLSR (Регрессия частичных наименьших квадратов) в Python3 с использованием предоставленного кода https://github.com/pgbrodrick/ensemblePLSR. Также предоставляются примеры данных.
Когда я пытаюсь запустить код, он выдает ошибку
>>> python3 ensemble_plsr.py example_settings.txt
Я использую Python (3.7.3), python modules scikit- учиться (0.20.2) и pandas (0.23.3).
