TypeError: Input 'y' of 'Add' Op has type float32 that does not match type int32 of argument 'x' tf.cast is useless

Question

today, I'm using TensorFlow to do some basic calculation, it suddenly has an error like below.

TypeError: Input 'y' of 'Add' Op has type float32 that does not match type int32 of argument 'x'.

I have tried to use tf.cast() to verify the type of the tensor, however, it seems to be useless which is based on that the types of the four variables of 're', 're2', 're3' and 're4' are just float32 according to the output:

re1: Tensor("mul:0", shape=(), dtype=float32)
re2: Tensor("mul_1:0", shape=(), dtype=float32)
re3: Tensor("mul_4:0", shape=(), dtype=float32)
re4: Tensor("mul_7:0", shape=(), dtype=float32)

now, I don't know how to deal with the problem. anyone can give me a hand? Any suggestion will be appreciated!!

here are some relative codes

re=(fc4[i][2]-fc4[i][0])*(fc4[i][3]-fc4[i][1])
re2=(bbox[i][2] - bbox[i][0]) * (bbox[i][3] - bbox[i][1])
re3=pro_x * (fc4[i][2] - fc4[i][0]) * pro_y * (fc4[i][3] - fc4[i][1])
re4=(pro_x*(fc4[i][2]-fc4[i][0])*pro_y*(fc4[i][3]-fc4[i][1]))  print("re1:",re)  
print("re2:",re2)
print("re3:",re3)  
print("re4:",re4)
overate=re4/(re+re2-re3)

the complete error is

Answer 1

Modify:

sum=tf.add(sum,overate)

To:

sum=tf.add(tf.cast(sum, overate.dtype),overate)
