[英]No module named 'sklearn.neighbors._base'
I have recently installed imblearn package in jupyter using我最近在 jupyter 中安装了 imblearn 包
!pip show imbalanced-learn
But I am not able to import this package.但我无法导入这个包。
from tensorflow.keras import backend
from imblearn.over_sampling import SMOTE
I get the following error我收到以下错误

I checked the sklearn package, it contains base module, not _base.我检查了 sklearn 包,它包含基本模块,而不是 _base。 But modifying it may not be the right solution.但是修改它可能不是正确的解决方案。 Any other solution to fix this issue.解决此问题的任何其他解决方案。
Previous sklearn.neighbors.base
has been renamed to sklearn.neighbors._base
in version 0.22.1 .以前的sklearn.neighbors.base
已在sklearn.neighbors._base
版本中重命名为sklearn.neighbors._base 。
You have probably a version of scikit-learn older than that.您可能有一个比这更旧的 scikit-learn 版本。 Installing the latest release solves the problem:安装最新版本解决了这个问题:
pip install -U scikit-learn
or或者
pip install scikit-learn==0.22.1
If in case you want to persist with the latest version of scikit-learn, add the following code to your script or execute the following code in your environment before installing imblearn如果您想坚持使用最新版本的 scikit-learn,请在安装 imblearn 之前将以下代码添加到您的脚本或在您的环境中执行以下代码
import sklearn.neighbors._base
sys.modules['sklearn.neighbors.base'] = sklearn.neighbors._base
This has to be after这必须在
pip install sklearn
or in a notebook environment:或在笔记本环境中:
!pip install sklearn
This problem stems from the fact that certain modules are named with an underscore in the newer scikit-learn releases这个问题源于这样一个事实,即某些模块在较新的 scikit-learn 版本中用下划线命名
I had a similar problem trying to import SMOTE from imblearn.over_sampling
and my version of scikit-learn was up to date (0.24.1).我在尝试从imblearn.over_sampling
导入imblearn.over_sampling
遇到了类似的问题,我的 scikit-learn 版本是最新的 (0.24.1)。 What worked for me was:对我有用的是:
First I downgraded my scikit learn version to 0.22.1 using首先,我使用
pip install scikit-learn==0.22.1
Next, I updated the imbalanced-learn package using:接下来,我使用以下方法更新了不平衡学习包:
pip install -U imbalanced-learn
That uninstalled scikit-learn-0.22.1, installed the updated version (scikit-learn-0.24.1), and updated the imbalanced-learn package.卸载了 scikit-learn-0.22.1,安装了更新版本 (scikit-learn-0.24.1),并更新了不平衡学习包。 Everything worked fine thereafter.此后一切正常。
If it is in a particular env, you must copy the _base
file or base
file to the env from package file.如果它在特定的 env 中,则必须将_base
文件或base
文件从包文件复制到 env。
I had the same problem in my tensorflow env.我在我的 tensorflow 环境中遇到了同样的问题。 I just copied _base
and base
file to my tensorflow env and worked.我只是将_base
和base
文件复制到我的 tensorflow 环境中并工作。
