What's matter? NameError

Question

what's mean? NameError: name 'make_blobs' is not defined I don't understand... plz help..

from sklearn.cluster import AgglomerativeClustering
X, y = make_blobs(random_state=1)
    
agg = AgglomerativeClustering(n_clusters=3)
assignment = agg.fit_predict(X)
    
mglearn.discrete_scatter(X[:, 0], X[:, 1], assignment)
plt.legend(["cluster 0", "cluster 1", "cluster 2"], loc="best")
plt.xlabel("feature 0")
plt.ylabel("feature 1")

Answer 1

You haven't imported it yet. Use:

from sklearn.datasets import make_blobs

Answer 2

I assume you meant to use sklearn.data_sets.make_blobs ? You should import that explicitly and use it appropriately.
