load_dygraph

paddle.fluid.dygraph.load_dygraph(model_path)[源代码]

该接口尝试从磁盘中加载参数或优化器的 dict

该接口会同时加载 model_path + ".pdparams"model_path + ".pdopt" 中的内容。

参数:
  • model_path (str) – 保存state_dict的文件前缀。该路径不应该包括后缀 .pdparams.pdopt

返回: 两个 dict ,即从文件中恢复的参数 dict 和优化器 dict

  • para_dict: 从文件中恢复的参数 dict
  • opti_dict: 从文件中恢复的优化器 dict

返回类型: tuple(dict, dict)

代码示例

import paddle.fluid as fluid

with fluid.dygraph.guard():
    emb = fluid.dygraph.Embedding( "emb", [10, 10])
    state_dict = emb.state_dict()
    fluid.save_dygraph( state_dict, "paddle_dy")
    adam = fluid.optimizer.Adam( learning_rate = fluid.layers.noam_decay( 100, 10000) )
    state_dict = adam.state_dict()
    fluid.save_dygraph( state_dict, "padle_dy")

    para_state_dict, opti_state_dict = fluid.load_dygraph( "paddle_dy")
