| ```python Depend is used for processing side-effect operations.

Supported Platforms: ``Ascend`` ``GPU`` ``CPU`` ``` | ```python Depend is used for processing dependency operations. In some side-effect scenarios, we need to ensure the execution order of operators. In order to ensure that operator A is executed before operator B, it is recommended to insert the Depend operator between operators A and B. Previously, the ControlDepend operator was used to control the execution order. Since the ControlDepend operator will be deprecated from version 1.2, it is recommended to use the Depend operator instead. The replacement method is as follows:: a = A(x) ---> a = A(x) b = B(y) ---> y = Depend(y, a) ControlDepend(a, b) ---> b = B(y) Inputs: - **value** (Tensor) - the real value to return for depend operator. - **expr** (Expression) - the expression to execute with no outputs.
