sklearn 没有._version_的属性
我的python环境是：
$python
Python 3.7.6 (default, Jan 8 2020, 13:42:34)
[Clang 4.0.1 (tags/RELEASE_401/final)] :: Anaconda, Inc. on darwin
Type "help", "copyright", "credits" or "license" for more information.
我的scikit-learn 版本是
$ pip install -U scikit-learn
Requirement already satisfied: scikit-learn in /Users/hjma/anaconda3/lib/python3.7/site-packages (1.0.2)
Requirement already satisfied: numpy>=1.14.6 in /Users/hjma/anaconda3/lib/python3.7/site-packages (from scikit-learn) (1.21.6)
Requirement already satisfied: scipy>=1.1.0 in /Users/hjma/anaconda3/lib/python3.7/site-packages (from scikit-learn) (1.4.1)
Requirement already satisfied: joblib>=0.11 in /Users/hjma/anaconda3/lib/python3.7/site-packages (from scikit-learn) (1.3.2)
Requirement already satisfied: threadpoolctl>=2.0.0 in /Users/hjma/anaconda3/lib/python3.7/site-packages (from scikit-learn) (3.1.0)
我在python3.7的环境中运行：
import sklearn
print(sklearn.version)
得到的结果是：
Traceback (most recent call last):
File "", line 1, in
AttributeError: module 'sklearn' has no attribute 'version'
以及
print(sklearn._version_)
Traceback (most recent call last):
File "", line 1, in
AttributeError: module 'sklearn' has no attribute 'version'
请教一下，是什么原因
