What are the methods for saving and loading models in the PaddlePaddle framework?

The PaddlePaddle framework comes with the methods paddle.save and paddle.load for saving and loading models.

Save model:

import paddle

# 定义模型
model = paddle.Model()
# ...
# 训练模型
# ...

# 保存模型
paddle.save(model.state_dict(), 'model.pdparams')

Load model:

import paddle

# 加载模型
state_dict = paddle.load('model.pdparams')
model.set_state_dict(state_dict)

In the code example above, the paddle.save function is used to save the model’s parameters to the file model.pdparams, and the paddle.load function is used to load the model parameters and set them to the model.
