You are running 32-bit Python on a 64-bit OS(mac) and XGBoost Library could not be loaded. Likely causes, Mac

I am trying to run below code in mac.

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

It is giving me below error. Please help me, I have been trying to solve this issue more than two days. But no luck.

The error popped up are shown below,

Solution

I had the same issue but solved it by running the flowing command on terminal

brew install libomp
