在python中安装Imblearn时找不到版本错误

Question

我正在尝试安装Imblearn，用于在python中执行SMOTE操作。我已经尝试安装imblearn软件包有一段时间了。但我经常犯错误。以下是我尝试过的命令，

pip install imblearn

pip install git+https://github.com/fmfn/UnbalancedDataset

以下是我所犯的错误，

Collecting imblearn

ERROR: No matching distribution found for scikit-learn>=0.21 (from imbalanced-learn->imblearn)

因此，由于数据严重不平衡，我无法继续我的建模部分。有人能帮我安装这个包裹吗？如果不是，在python中有哪些替代的方法来执行攻击？

Answer 1

Scikit-学习0.20是支持Python2.7的最后一个版本。Scikit-学习0.21及更高版本需要Python 3.5或更高版本。

请参阅以下链接：

https://pypi.org/project/scikit-learn/0.21.0/

我建议使用Python3

Answer 2

命令已更改。如下所示
