ModuleNotFoundError:没有名为"sklearn.utils._joblib"的模块

问题描述

我在Anaconda Jupyter笔记本平台上使用python 3.6.我的电脑使用win 8.1作为操作系统.

I'm using python 3.6 on on Anaconda Jupyter notebooks platform. My pc uses win 8.1 as OS.

我正尝试使用以下几行从sklearn导入PCA:

I was trying to import PCA from sklearn using the following lines:

import sklearn
from sklearn import decomposition 
from sklearn.decomposition import PCA 

第三行返回模块错误:ModuleNotFoundError: No module named 'sklearn.utils._joblib'

the third line returns a Module error: ModuleNotFoundError: No module named 'sklearn.utils._joblib'

奇怪的是，我找不到此错误的任何记录在线！我将不胜感激.我在下面复制了完整的错误消息:

Strangely, I couldn't find any record on this error online! I'd appreciate any help. I copied the complete error message below:

推荐答案

2019年5月对PR的评论提到他们想抛弃它.

从2019年6月开始， sklearn.utils._joblib不再是一个东西.

As of June 2019, sklearn.utils._joblib is no longer a thing.

• 很难说为什么此代码在三月份无法使用，因为它仍然是支持 May 版本

分析:您的环境中有旧版本.也许pip install -r requirements.txt让您满意，超越了工作版本，还是其他的东西.

Analysis: you've got old versions in your environment. Perhaps pip install -r requirements.txt got you, overriding the working version, or something else.

建议:创建一个新的conda环境，在该环境中重新安装sklearn和joblib(通过conda install scikit-learn joblib)并继续前进.

Recommendation: make a new conda environment, reinstall sklearn and joblib (via conda install scikit-learn joblib) in that environment and move forward.
