【中文标题】sklearn_extra 安装问题

【发布时间】：2020-04-24 08:48:05

【问题描述】：

[输入]：

from sklearn_extra.cluster import KMedoids

[出]：

ModuleNotFoundError: No module named 'sklearn_extra'

然后，我尝试通过安装 sklearn_extra

[输入]：

python -m pip install sklearn_extra

[出]：

ERROR: Could not find a version that satisfies the requirement sklearn_extra (from versions: none)
ERROR: No matching distribution found for sklearn_extra

然后，我去了网站的安装部分（https://scikit-learn-extra.readthedocs.io/en/latest/install.html）并按照它说的做了：

Installation
Dependencies
scikit-learn-extra requires,

Python (>=3.5)

scikit-learn (>=0.21), and its dependencies

Cython (>0.28)

User installation
Latest development version can be installed with,

pip install https://github.com/scikit-learn-contrib/scikit-learn-extra/archive/master.zip

[输入]：

pip install https://github.com/scikit-learn-contrib/scikit-learn-extra/archive/master.zip

[出]：

  ERROR: Command errored out with exit status 1:

      class RegexFlag(enum.IntFlag):
  AttributeError: module 'enum' has no attribute 'IntFlag'

我检查了 Cython、Python 和 sklearn 的版本，它们满足要求的范围。

编辑：感谢 Balraj Ashwatt 的评论，解决方案是为我卸载 enum34。

pip uninstall -y enum34

然后我就可以安装 sklearn_extra

【问题讨论】：

我们可以得到完整的日志吗？

这些链接可能会有所帮助：1) github.com/iterative/dvc/issues/1995#issuecomment-496661430 2) ***.com/questions/43124775/… 3)

你确定你已经安装到合适的环境中了吗？最近因为安装到系统 python 而不是项目一而与jupyter 混淆

@A.Ametov 我想我的问题是通过我这边的命令 pip uninstall -y enum34 解决的

【参考方案1】：

我试过了，

pip install scikit-learn-extra

这对我来说似乎没问题 ！

【参考方案2】：

卸载 enum34 对我有用，然后我能够安装 sklearn_extra

pip uninstall -y enum34

【参考方案3】：

试试这个命令：

conda install -c conda-forge scikit-learn-extra
