just strange

```
%%time
xgb = xgb.XGBRegressor(n_estimators=500, learning_rate=0.07, gamma=0, subsample=0.75, colsample_bytree=1,
max_depth=7, tree_method='gpu_exact')
```

this code takes around Wall time: 866 ms.

but when I do the gridsearchCV it does not goes to the next step

even though I gave only one parameter

```
%%time
xgb = XGBClassifier(tree_method='gpu_exact',verbose_eval=True, silence=False)
kfold = StratifiedKFold(n_splits=10, random_state=0)
xgb_param_grid = {
'learning_rate': [0.08,0.09],
'random_state': [0],
'max_depth': [8,9],
'n_estimators': [400,500]
}
xgbGrid = gsRFC = GridSearchCV(xgb,param_grid = xgb_param_grid, cv=5, scoring="neg_mean_squared_error", n_jobs= 10, verbose = 1)
xgbGrid.fit(X,y)
xgb_best = xgbGrid.best_estimator_
for my understanding, this should not take that long.<br/>
it d
```

does not go to the next step I do not sure this even working or not

it stop with

Fitting 5 folds for each of 8 candidates, totalling 40 fits [Parallel(n_jobs=10)]: Using backend LokyBackend with 10 concurrent workers.

data set size is (15035, 22) am I doing something wrong?
