python-3.x - 您在 64 位操作系统（mac）上运行 32 位 Python，无法加载 XGBoost 库。可能的原因，Mac

问题描述

我正在尝试在 mac 中运行以下代码。

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

它给了我以下错误。请帮助我，我已经尝试解决这个问题超过两天了。但没有运气。

弹出的错误如下图所示，

解决方案

我有同样的问题，但通过在终端上运行流动命令解决了它

brew install libomp
