Problem:

I want to get the probability of the Logistic Regression model, while use cross-validation.
But now I'm only able to get the scores of the model, can u help me to get the probabilities?
please save the probabilities into a list or an array. thanks.

A:

<code>
import numpy as np
import pandas as pd
from sklearn.linear_model import LogisticRegression
from sklearn.model_selection import StratifiedKFold
X, y = load_data()
assert type(X) == np.ndarray
assert type(y) == np.ndarray
cv = StratifiedKFold(5).split(X, y)
logreg = LogisticRegression()
</code>
proba = ... # put solution in this variable
BEGIN SOLUTION
<code>

library

Sklearn
