ImportError: cannot import name '_validate_lengths' 解决方法

numpy升级以后遇到以上错误，版本变化函数名称发生变化：根据错误提示点击到arrycrop.py文件

加入下面语句

修改前：

import numpy as np
from numpy.lib.arraypad import _validate_lengths

 

 修改后

import numpy as np
from distutils.version import LooseVersion as Version
old_numpy = Version(np.__version__) < Version('1.16')
if old_numpy:
from numpy.lib.arraypad import _validate_lengths
else:
from numpy.lib.arraypad import _as_pairs
