虹膜数据集拆分功能未编译？

Question

我正在尝试使用 train_test_split 函数随机拆分 2 个数据集（numpy 数组），但由于某种原因我的代码没有编译。

# Iris data set, hello world of Machine Learning
#classes: possible outcomes
#label: for each data point, its classification
# this is a three class classification problem

import numpy as np
import matplotlib.pyplot as plt
import pandas as pd
from sklearn.datasets import load_iris
from sklearn.model_selection import train_test_split

X_train, X_test,y_train y_test = train_test_split(iris_dataset['data'], 
iris_dataset['target'],random_state=0)

错误信息：

Answer 1

在y_train和y_test之间添加逗号：

X_train, X_test,y_train y_test = train_test_split(iris_dataset['data'], 
iris_dataset['target'],random_state=0)
