normalize_program¶

paddle.static. normalize_program ( program, feed_vars, fetch_vars ) [source]

Api_attr

Static Graph

Normalize/Optimize a program according to feed_vars and fetch_vars.

Parameters

• program (Program) – Specify a program you want to optimize.

• feed_vars (Variable | list[Variable]) – Variables needed by inference.

• fetch_vars (Variable | list[Variable]) – Variables returned by inference.

Returns

Normalized/Optimized 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())

# normalize main program.
program = paddle.static.default_main_program()
normalized_program = paddle.static.normalize_program(program, [image], [predict])
