I am getting next Warning:

D:ProgrammingPythonMLvenvlibsite-packagessklearnutilsdeprecation.py:77: DeprecationWarning: Function make_blobs is deprecated; Please import make_blobs directly from scikit-learn

warnings.warn(msg, category=DeprecationWarning)

even with this

from sklearn.datasets.samples_generator import make_blobs

And my simple code

# generate dataset

X, y = mglearn.datasets.make_forge()

# plot dataset

mglearn.discrete_scatter(X[:, 0], X[:, 1], y)

plt.legend(["Class 0", "Class 1"], loc=4)

plt.xlabel("First feature")

plt.ylabel("Second feature")

print("X.shape: {}".format(X.shape))

plt.show()

Function make_forge()

def make_forge():

# a carefully hand-designed dataset lol

X, y = make_blobs(centers=2, random_state=4, n_samples=30)

y[np.array([7, 27])] = 0

mask = np.ones(len(X), dtype=np.bool)

mask[np.array([0, 1, 5, 26])] = 0

X, y = X[mask], y[mask]

return X, y

Well, in make_blobs.py I found next thing

@deprecated("Please import make_blobs directly from scikit-learn")

def make_blobs(n_samples=100, n_features=2, centers=2, cluster_std=1.0,

           center_box=(-10.0, 10.0), shuffle=True, random_state=None):

Yes, I know that my code will succesfully compile even with this warning but I want to know why I`m getting this and why this is deprecated. Thanks for help

Use the following to import make_blobs that will not give you any warning.

from sklearn.datasets import make_blobs
