load_from_file¶

paddle.static. load_from_file ( path ) [source]

Load file in binary mode.

Parameters

path (str) – Path of an existed file.

Returns

Content of file.

Return type

bytes

Examples

import paddle
paddle.enable_static()
path_prefix = "./infer_model"
# 用户自定义网络，此处用 softmax 回归为例。
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())
# 序列化参数
serialized_params = paddle.static.serialize_persistables([image], [predict], exe)
# 将序列化之后的参数保存到文件
params_path = path_prefix + ".params"
paddle.static.save_to_file(params_path, serialized_params)
# 从文件加载序列化之后的参数
serialized_params_copy = paddle.static.load_from_file(params_path)
