Python3 Numpy np.where错误

import numpy as np

# 示例1：参数错误
arr = np.array([1, 2, 3])
condition = np.array([True, False, True])
result = np.where(condition, arr, 'error')  # 返回值类型错误

# 示例2：数组维度不匹配
arr1 = np.array([1, 2, 3])
arr2 = np.array([[4, 5, 6], [7, 8, 9]])
condition = np.array([True, False, True])
result = np.where(condition, arr1, arr2)  # 维度不匹配

# 示例3：数组类型不匹配
arr = np.array([1, 2, 3])
condition = np.array([True, False, True])
result = np.where(condition, arr, np.array(['a', 'b', 'c']))  # 数据类型不匹配

# 示例4：数组形状不匹配
arr1 = np.array([1, 2, 3])
arr2 = np.array([[4, 5, 6], [7, 8, 9]])
condition = np.array([True, False, True])
result = np.where(condition, arr1, np.broadcast_to(arr2, (2, 3)))  # 形状不匹配
