Я использую Spyder 3.3.2 и scikit-learn Версия: 0.20.1.Я запускаю скрипт, который начинает импорт DBSCAN:
from sklearn.cluster import DBSCAN
Первые два раза, когда я запускаю скрипт, он работает нормально.Тем не менее, в третий раз я неизменно получаю:
Traceback (most recent call last):

Если я запускаю скрипт в терминале, выполняя:
python MyScript.py
, все работает нормально, так что это должно быть проблемой сSpyder.Кроме того, ошибка повторяется, если я запускаю скрипт, содержащий только эту строку кода.
Заранее спасибо!
