[英]'numpy.ndarray' object has no attribute 'values' using reshape
I'm trying to reshape data into two-dimensional data structure so I can use it in Sklear, I keep getting an error 'numpy.ndarray' object has no attribute 'values' and when I tried removing values from-- Xtrain.values.reshape(-1, 1) I get another error saying: Reshape your data either using array.reshape(-1, 1) if your data has a single feature or array.reshape(1, -1) if it contains a single sample.我正在尝试将数据重塑为二维数据结构,以便可以在 Skear 中使用它,我不断收到错误“numpy.ndarray”object 没有属性“值”,当我尝试从 Xtrain.values 中删除值时.reshape(-1, 1) 我收到另一个错误消息:如果您的数据具有单个特征,则使用 array.reshape(-1, 1) 或 array.reshape(1, -1) 如果它包含单个特征,则使用 array.reshape(1, -1) 重塑您的数据样本。
import pandas as pd
import matplotlib.pyplot as plt
import numpy as np
data = pd.read_csv('loan_defaults.csv')
data = pd.get_dummies(data, drop_first=True)
data.groupby('default').mean()
data.corr()
defaultN = data.query('default == 0')
defaultY= data.query('default == 1')
from sklearn.model_selection import train_test_split
Xtrain, Xtest, ytrain, ytest = train_test_split(data.balance, data.default, random_state = 0)
Xtrain = Xtrain.values.reshape(-1, 1)
Xtest = Xtest.values.reshape(-1, 1)
from sklearn.linear_model import LogisticRegression
log_reg = LogisticRegression(class_weight="balanced")
log_reg.fit(Xtrain, ytrain)
log_reg.intercept_
log_reg.coef_
log_reg.predict_proba(100)
log_reg.predict(100)
No real need to add values after performing train_test_split
as the output is an array itself.执行
train_test_split
后无需添加值,因为 output 本身就是一个数组。 Simply try with:只需尝试:
Xtrain = Xtrain.reshape(-1,1)
Xtest = Xtest.reshape(-1,1)
