给定函数的错误:只能将大小为1的数组转换为Python标量

import numpy as np

# 示例1：数组维度不匹配
a = np.array([1, 2, 3])
b = np.array([[4, 5, 6], [7, 8, 9]])
c = a + b  # 报错：ValueError: operands could not be broadcast together with shapes (3,) (2,3)

# 示例2：数组形状不匹配
a = np.array([1, 2, 3])
b = np.array([[4, 5, 6]])
c = a + b  # 报错：ValueError: operands could not be broadcast together with shapes (3,) (1,3)

# 示例3：数组大小不匹配
a = np.array([1, 2, 3])
b = np.array([4, 5])
c = a + b  # 报错：ValueError: operands could not be broadcast together with shapes (3,) (2,)

# 示例4：数组数据类型不匹配
a = np.array([1, 2, 3])
b = np.array([4.0, 5.0, 6.0])
c = a + b  # 报错：TypeError: unsupported operand type(s) for +: 'int' and 'float'
