Python3泡菜：AttributeError：无法获取属性“ CHJ_tiny_obj”

Question

当我尝试使用python3 .pkl恢复pickle模型时：

>>> import pickle
>>> with open('./019-SUV.pkl', 'rb') as file:
...     pickle.load(file, encoding='latin1')

它提出了一个错误：

AttributeError: Can't get attribute 'CHJ_tiny_obj' on <module 'objloader' from  
'/home/xx/anaconda3/lib/python3.7/site-packages/objloader/__init__.py'>
