無法計算 Add 作為輸入 #1（從零開始）應該是一個 int32 張量，但它是一個雙張量 [Op:Add]

Question

import tensorflow as tf
a = tf.constant(6, name = 'constant_a')
b = tf.constant(3, name = 'constant_b')
c = tf.constant(10, name = 'constant_c')
d = tf.constant(5, name = 'constant_d')
mul = tf.multiply(a, b, name = 'mul')
div = tf.divide(c, d, name = 'div')

這一行給了我錯誤

addn = tf.add(mul, div)

InvalidArgumentError: cannot compute Add as input #1(zero-based) was expected to be a int32 tensor but is a double tensor [Op:Add]

Answer 1

addn = tf.add(mul, tf.cast(div, tf.int32))

這有助於

 tf.cast(
        x,
        dtype,
        name=None
    )

很抱歉問一個問題，如果那是愚蠢的！！！
