PCTExamples

 PCTExamples (config_file, min=True, early_termination=False,
              history=False, additional_props=None, render=False,
              video_params=None)

PCTExamples class provides methods to load a PCT hierarchy from a configuration file, summarize the hierarchy, get the configuration, draw the hierarchy, run the hierarchy for a specified number of steps, and close the environment. Attributes: hierarchy (PCTHierarchy): The loaded PCT hierarchy. env (Environment): The environment associated with the PCT hierarchy.

Usage Examples for PCTExamples.run_example

Below are several usage examples demonstrating the new keyword-argument-based interface for run_example.

# Basic run with MountainCar config
filename = 'testfiles/MountainCar/MountainCar-cdf7cc.properties'
result_basic = PCTExamples.run_example(filename)
result_basic

# Full featured run
result_full = PCTExamples.run_example(
    config_file=filename,
    run_hierarchy=True,
    render=False,
    early_termination=True,
    steps=5000,
    print_summary=False,
    return_config=False,
    verbose=False,
    image_params={'figsize': (16, 10), 'with_labels': True},
    video_params={'fps': 60, 'filename': '/tmp/mountaincar_demo.mp4'},
    plot_params={'plots_figsize': (14, 8), 'title_prefix': 'MountainCar_'}
)
result_full

# Just create image and get config
result_image = PCTExamples.run_example(
    config_file=filename,
    run_hierarchy=False,
    return_config=True,
    print_summary=False,
    # plot_params={'single_plot': True, 'plots': {'title': 'position_plot', 'plot_items': ['position']}}
)
result_image

PCTExamples.run_example('', display_usage=True)

            PCTExamples.run_example() Usage:
            
            Basic usage:
                PCTExamples.run_example('testfiles/MountainCar/MountainCar-cdf7cc1497ad143c0b04a3d9e72ab783.properties')
            
            With options:
                PCTExamples.run_example(
                    config_file='testfiles/MountainCar/MountainCar-cdf7cc1497ad143c0b04a3d9e72ab783.properties',
                    run_hierarchy=True,      # Run the hierarchy
                    render=True,             # Render environment
                    image_params={...},      # Create hierarchy diagram if not None
                    video_params={...},      # Create video if not None
                    plot_params={...},       # Create plots if not None
                    early_termination=True,  # Enable early termination
                    steps=1000,              # Override step count
                    print_summary=True,      # Print hierarchy summary
                    return_config=True,      # Return configuration
                    verbose=True             # Verbose output
                )
            
            Returns dictionary with results and any requested outputs.
