deserialize_persistables¶

paddle.static. deserialize_persistables ( program, data, executor ) [source]

Deserialize given data to parameters according to given program and executor.

Parameters

• program (Program) – program that contains parameter names (to deserialize).

• data (bytes) – serialized parameters.

• executor (Executor) – executor used to run load op.

Returns

deserialized program.

Return type

Program

Examples

>>> import paddle

>>> paddle.enable_static()

>>> path_prefix = "./infer_model"

# User defined network, here a softmax regession example
>>> image = paddle.static.data(name='img', shape=[None, 28, 28], dtype='float32')
>>> label = paddle.static.data(name='label', shape=[None, 1], dtype='int64')
>>> predict = paddle.static.nn.fc(image, 10, activation='softmax')

>>> loss = paddle.nn.functional.cross_entropy(predict, label)

>>> exe = paddle.static.Executor(paddle.CPUPlace())
>>> exe.run(paddle.static.default_startup_program())

# serialize parameters to bytes.
>>> serialized_params = paddle.static.serialize_persistables([image], [predict], exe)

# deserialize bytes to parameters.
>>> main_program = paddle.static.default_main_program()
>>> deserialized_params = paddle.static.deserialize_persistables(main_program, serialized_params, exe)
