Python运行出现DeprecationWarning
Python版本问题出现DeprecationWarning
Python运行出现DeprecationWarning今天运行 py 时出现下面的问题：
DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated since Python 3.3,and in 3.9 it will stop working
是这个语句出现的问题：
from collections import Iterable
好像是 py 版本更新以后包发生了变化，只需要改一下包名就行：
collections->collections.abc
Python版本问题出现DeprecationWarning
sklearn.cross_validation.cross_val_score（）
例如：
from sklearn import cross_validation
D:\Anaconda3\lib\site-packages\sklearn\cross_validation.py:41: DeprecationWarning: This module was deprecated in version 0.18 in favor of the model_selection module into which all the refactored classes and functions are moved. Also note that the interface of the new CV iterators are different from that of this module. This module will be removed in 0.20. "This module will be removed in 0.20.", DeprecationWarning)
改为
from sklearn.model_selection import cross_val_score
以上为个人经验，希望能给大家一个参考，也希望大家多多支持易知道(ezd.cc)。
