If it don't work, maybe you need to install "imblearn" package.

如果它不起作用，也许您需要安装“imblearn”包。

I've tried all of these solutions and nothing worked, only thing that worked for me is changing the kernel. I'm running Jupyter on Amazon Sagemaker and I changed the kernel from pyhton3 to pytorch36 and it worked just fine. Hope this helps

我已经尝试了所有这些解决方案，但没有任何效果，唯一对我有用的是更改内核。我在 Amazon Sagemaker 上运行 Jupyter，并将内核从 pyhton3 更改为 pytorch36，并且运行良好。希望这可以帮助

pip install -U imbalanced-learnshould work, although make sure you've met the dependencies for numpy, scipy and scikit-learn.

pip install -U imbalanced-learn应该可以工作，但请确保您已满足 numpy、scipy 和 scikit-learn 的依赖项。
