Sklearn Model 的 method.fit()

Question

Does a Sklearn model's.fit () method reset the weights on each call? Does the pice of code below its all right? I saw it somewhere for cross validation and I dont know if it makes sense.

from sklearn.neural_network import MLPRegressor
from sklearn.datasets import make_regression
from sklearn.model_selection import train_test_split

X, y = make_regression(n_samples=200)
regr = MLPRegressor(solver='sgd', max_iter=150)

for i in range(5):
    X_train, X_test, y_train, y_test = train_test_split(X, y)
    regr.fit(X_train, y_train)

Thank you.

Yes, it resets the weights, as you can see here on the documentation

Calling fit() more than once will overwrite what was learned by any previous fit()
