Program¶

class paddle.static. Program

Create Python Program. Program is an abstraction of model structure, divided into computational graphs and weights. The Program has a main block that stores the computational graphs.

A set of Program usually contains startup program and main program. A startup program is set to contain some initial work, eg. initialize the Parameter, and the main program will contain the network structure and vars for train.

A set of Program can be used for test or train, in train program , Paddle will contain all content to build a train network, in test program Paddle will prune some content which is irrelevant to test, eg. backward ops and vars.

Notes:

we have default_startup_program and default_main_program by default, a pair of them will shared the parameters. The default_startup_program only run once to initialize parameters, default_main_program run in every mini batch and adjust the weights.

Returns

An empty Program.

Return type

Program

Examples

>>> import paddle
>>> import paddle.static as static

>>> paddle.enable_static()

>>> main_program = static.Program()
>>> startup_program = static.Program()
>>> with static.program_guard(main_program=main_program, startup_program=startup_program):
...    x = static.data(name="x", shape=[-1, 784], dtype='float32')
...    y = static.data(name="y", shape=[-1, 1], dtype='int32')
...    z = static.nn.fc(name="fc", x=x, size=10, activation="relu")
>>> print("main program is: {}".format(main_program))
>>> print("start up program is: {}".format(startup_program))
