问题


I am using xgb api for python and when trying to do xgb.cv I get the following error,

param = {'max_depth': 6, 'eta': 0.1,'objective' :'reg:squarederror','subsample':0.8 ,'gamma':0,
         'colsample_bytree':1,'nthread':cores,'base_score':y_train.mean(),'eval_metric':'rmse'}
num_round = 1
evallist = [(test, 'eval'), (train, 'train')]


xgb.cv(param, train, num_round, nfold=5,
           metrics={'error'}, seed=0,
           callbacks=[xgb.callback.print_evaluation(show_stdv=True)])

            959 
        
        OSError: [WinError -529697949] Windows Error 0xe06d7363

I already tried to install and uninstall XGB but I don't think that is the problem because I can train, the problem is when I try to do cross validation.

I am using:

Python : 3.7.3 (default, Apr 24 2019, 15:29:51) [MSC v.1915 64 bit (AMD64)]

xgb.version '1.1.0'

Update 20200831

What it worked for me was:

1. Uninstall xgboost

2. Upgrade pip

3. Reinstall xgboost using pip3 install xgboost
