我正在尝试运行下面的代码。这是https://github.com/krishnaik06的 GitHub 代码。

jupyter笔记本的链接如下。

我无法加载 xgboost 的地方

尝试在单元格下方运行，它显示一些错误。

## Hyperparameter optimization using RandomizedSearchCV
from sklearn.model_selection import RandomizedSearchCV, GridSearchCV
import xgboost

错误：

Likely causes:

我尝试过的：

1. 卸载的 anaconda
2. 安装了 anaconda 和 64 位 python。

还是同样的错误

Answer 1

首先，我通过pip安装了xgboost，我得到了同样的错误。然后，我通过代码：卸载了它pip uninstall xgboost，并通过代码：再次通过anaconda安装了它conda install py-xgboost。现在我可以import xgboost 没有错误了。
