信用卡逻辑回归报错
代码：
import pandas as pd

data=pd.read_csv("datasets/credit-a.csv",header=None)
print(data.head())
print(data.iloc[:,-1].value_counts())#.iloc[]与loc一样，中括号里面也是先行后列，行列标签用逗号分割
#data.iloc[:,-1].replace(-1,0)
x=data.iloc[:,:-1]#所有行，除了最后一列的所有列
y=data.iloc[:,-1].replace(-1,0)#用0替换掉改列所有的-1
model=tf.keras.Sequential()
