ValueError: Tensor("Placeholder:0", shape=(), dtype=float32) must be from the same graph as Tensor("total:0", shape=(), dtype=resource)

hi, i am trying to deploy my model via flask rest api but i am facing issues in deploying my custom model.issue is mentioned in title, if any of you can help me please!
