ModuleNotFoundError: No module named ‘xxx’

ModuleNotFoundError: No module named'xxx' is 
not in pycharm, so the upper level directory cannot be added to sources root. 
Method 1: So you can only add the path location in sys before importing

import os
import sys

curPath = os.path.abspath(os.path.dirname(__file__))
rootPath = os.path.split(curPath)[0]
sys.path.append(os.path.split(rootPath)[0])
