TypeError: __init__() 得到了一个意外的关键字参数“n_folds”

Question

results = []    
names = []    
for name, model in models:    
    kfold = model_selection.KFold(n_splits=num_instances, n_folds=num_folds, random_state=seed)    
    cv_results = model_selection.cross_val_score(model, X_train, Y_train, cv=kfold, scoring=scoring)    
    results.append(cv_results)    
    names.append(name)    
    msg = "%s: %f (%f)" % (name, cv_results.mean(), cv_results.std())    
    print(msg) 

我猜随着新的更新， n_folds不再在 Kfold 中使用。 谁能帮我解决这个问题？

Answer 1

在更新的库中， n_folds参数被重命名为n_splits ：
