Python "AttributeError: модуль 'numpy' не имеет атрибута 'core'" из-за импорта

Question

Следующий код работал правильно, пока я не добавил from joblib import Parallel, delayed к этой строке в numpy пакете https://github.com/numpy/numpy/blob/master/numpy/core/fromnumeric.py#L19. Кто-нибудь знает, как его решить? Я хочу использовать библиотеку joblib в пакете numpy. Спасибо!

from sklearn import preprocessing
import numpy as np

X_train = np.random.randn(4, 4)
print(X_train)

X_scaled = preprocessing.scale(X_train)

Сообщение об ошибке выглядит следующим образом:
