ModuleNotFoundError:没有名为“sklearn.utils._joblib"的模块 [英] ModuleNotFoundError: No module named 'sklearn.utils._joblib'

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.

我试图使用以下几行从 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'

奇怪的是，我在网上找不到有关此错误的任何记录！我很感激任何帮助.我复制了以下完整的错误消息:

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

直接安装导入joblib:

Install and import joblib directly:

!pip install joblib
import joblib
