Jupyter：安装后没有名为“imblearn”的模块

Question

I installed "imbalanced-learn" (version 0.3.1) on ANACONDA Navigator. When I ran an example from the imbalanced-learn website using Jupyter (Python 3):

from imblearn.datasets import make_imbalance
from imblearn.under_sampling import NearMiss
from imblearn.pipeline import make_pipeline
from imblearn.metrics import classification_report_imbalanced

I got an message regarding "ModuleNotFoundError".

ModuleNotFoundError: No module named 'imblearn'

How could I resolve this?

Answer 1

Problems importing imblearn python package on ipython notebook

Found the answer here. This worked for me

conda install -c glemaitre imbalanced-learn

Answer 2

This worked for me:

!pip install imblearn

Then, I was able to import SMOTE package.

from imblearn.over_sampling import SMOTE

Answer 3

I have faced the same problem and I installed imblearn first by typing this command:

!pip install imblearn  

in jupyter notebook and then it is fine

Answer 4

Just in case someone encounters this problem on Google Cloud Jupyter notebook instances, using pip3 to install imblearn made it work for me, after failing with pip command:

pip3 install imblearn

or directly in the notebook:

!pip3 install imblearn

You should see imblearn (0.0) and imbalanced-learn (4.3) in your pip list.

NB! Make sure to reload your notebooks (File -> Close and Shutdown), otherwise it might fail to import the library after install.

Answer 5

conda install -c conda-forge imbalanced-learn 

它只是担心问题

Answer 6

imbalanced-learn is currently available on the PyPi's reporitories and you can install it via pip:

pip install -U imbalanced-learn

The package is release also in Anaconda Cloud platform:

conda install -c conda-forge imbalanced-learn

Answer 7

One of the below four commands should work. Only the 3rd worked for me.

conda install -c conda-forge imbalanced-learn

conda install -c conda-forge/label/gcc7 imbalanced-learn

conda install -c conda-forge/label/cf201901 imbalanced-learn

conda install -c conda-forge/label/cf202003 imbalanced-learn

Answer 8

Just check if you antivirus or firewall is blocking the download process. I too had the same issue. This happens when you try to install through Anaconda. During the installation process there occurs a permission error. This is probably due to antivirus blocking the download process.

Answer 9

打开 Anaconda Prompt 并输入

pip install imbalanced-learn --user

Answer 10

我正在使用 Jupyter 笔记本，这对我有用：

pip install imblearn

Answer 11

我在我的 Jupyter Notebook 中使用了这段代码，它运行良好。

! pip install imbalanced-learn

Answer 12

Use this:

!pip3 install imblearn --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host files.pythonhosted.org --user

This will override SSL certificate requirement and complete the installation.

If after this you still get the error, restart the kernel and run just the import code, not this install command again. That will import imblearn successfully.

Answer 13

The below code is the most updated one:

conda update -n base -c defaults conda

from imblearn.over_sampling import SMOTE

Answer 14

I needed to upgrade pip first:

pip3 install --upgrade pip

then, and only then, was I able to install imbalanced-learn:

pip3 install imbalanced-learn
