Meanwhile, it provides necessary API to trigger EagerParamBase Lazy Initialization and get startup Program. Examples: .. code-block:: python >>> from paddle import LazyGuard >>> from paddle.nn import Linear >>> with LazyGuard(): ... # w and b are initialized lazily and have no memory. ... net = Linear(10, 10) ... >>> for param in net.parameters(): ... # Initialize param and allocate memory explicitly. ... param.initialize() cCstƒ ¡dS)a¼ Construct instance from class_obj by Lazy Initializing parameters.
