LazyGuard¶

class paddle. LazyGuard [source]

LazyGuard is a wrapper interface for nn.Layer, it forwards the construct process of user defined Layer. Meanwhile, it provides necessary API to trigger EagerParamBase Lazy Initialization and get startup Program.

Examples

>>> 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()
