如何为 Python 安装 SHAP (Shapley)

Question

尝试使用安装 Shapley 包（在 R 中可用）

但出现错误：

安装 xgboost 同样的故事

Answer 1

您是否打算安装 shapely ( https://pypi.org/project/Shapely/ )？在 python 中，你可以通过执行 pip install shapely 来安装 shapely

对于 Windows，可以通过从 http://www.lfd.uci.edu/~gohlke/pythonlibs/#shapely 下载 .whl 来安装 shapley，然后执行

pip install <name of whl file>

或者，如果您使用的是 anaconda，则可以使用 conda-forge 来保持身材

conda config --add channels conda-forge conda install shapely

---

要安装 xgboost，请参阅 http://xgboost.readthedocs.io/en/latest/python/python_intro.html 为此，您可能需要 gcc（c/c++ 编译器）或等效的 Microsoft 替代方案。

对于带有 conda 的 xgboost，您可以看到这个 stackoverflow.com/questions/35139108/… 或者简单地做 conda install py-xgboost

您是否正在尝试安装 shap - 一个用于解释机器学习模型的库？如果是这样使用

pip install shap

有关详细信息，请参阅 shap 文档： https ://pypi.org/project/shap/
