Found input variables with inconsistent numbers of samples 30 120

Question

Hello, I am doing Your Machine Learning Course on Youtube. When I running my first code from your video I am facing This Value Error.

Here is my Code: Dataset = Iris Dataset

seed = 6
scoring = 'accuracy'
models = []
models.append(('LR', LogisticRegression()))
models.append(('LDA', LinearDiscriminantAnalysis()))
models.append(('KNN', KNeighborsClassifier()))
models.append(('CART', DecisionTreeClassifier()))
models.append(('NB', GaussianNB()))
models.append(('SVM', SVC()))

results = []
names = []
for name, model in models:
    kfold = model_selection.KFold(n_splits=10, 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)

Hi@Kinjal,

There is a problem with your X and y variable. You need to check the shape of your variables. Most probably, your y variable is in 1D. If you face the same error, then paste your complete code here.
