codigo n funciona

eu estou no python 3 e ele esta dando erro

from sklearn.naive_bayes import MultinomialNB
from dados import ler_dados

X, Y = ler_dados()

IA = MultinomialNB()

IA.fit(X,Y)

previsao = IA.predict(X)

diferencas = previsao - Y

tc = [d for d in diferencas if d == 0]

tx = len(tc)

tl = len(X)

ac = 100.00*tx/tl

print(diferencas)

print(tx)
print(ac)

esse aqui permite a leitura dos dados

import csv

def ler_dados():
    X = []
    Y = []

    arquivo = open('acesso.csv','r')
    leitor = csv.reader(arquivo)

    next(leitor)

    for home, como_funciona, contato, comprou in leitor:
        X.append([int(home), int(como_funciona), int(contato)])
        Y.append([int(comprou)])

    return X, Y

esse aqui são os dados

home,como_funciona,contato,comprou
