Save and Restore Parameters

Goal of this tutorial:

• Learn how to save and restore parameters.

Example

Sometimes we need to save the parameters into a file and reuse them later on. PARL provides operators to save parameters to a file and restore parameters from a file easily. You only need several lines to implement this.

Here is a demonstration of usage:

agent = AtariAgent()
# save the parameters of agent to ./model_dir
agent.save('./model_dir')
# restore the parameters from ./model_dir to agent
agent.restore('./model_dir')

# restore the parameters from ./model_dir to another_agent
another_agent = AtariAgent()
another_agent.restore('./model_dir')
