如何创建从tf.Tensor继承的新类？

import tensorflow as tf

class MyTensor(tf.Tensor):
    pass

class MyTensor(tf.Tensor):
    def custom_method(self):
        # 自定义方法的实现
        pass

    @property
    def custom_property(self):
        # 自定义属性的实现
        pass

class MyTensor(tf.Tensor):
    def __init__(self, input_data, custom_arg):
        super().__init__(input_data)
        self.custom_arg = custom_arg

    def __add__(self, other):
        # 自定义加法操作的实现
        pass

    def __mul__(self, other):
        # 自定义乘法操作的实现
        pass

x = tf.constant([1, 2, 3])
my_tensor = MyTensor(x, custom_arg=10)
result = my_tensor + 5
