In consistent control/physics frequency desciption in tasks.py and maze.py

[yli2565]

In tasks.py

# Slow control (4Hz), so that agent without HRL has a chance.
# Native control would be ~20Hz, so this corresponds roughly to action_repeat=5.
DEFAULT_CONTROL_FREQ = 4.0

...

   task = MemoryMazeTask(
        ...
        control_timestep=1.0 / control_freq,
        ...
    )

So the control_timstep parameter is default to 0.25, which is 4Hz as intended

However, in maze.py

DEFAULT_CONTROL_TIMESTEP = 0.025
DEFAULT_PHYSICS_TIMESTEP = 0.005
...
class MemoryMazeTask(random_goal_maze.NullGoalMaze):
    # Adapted from dm_control.locomotion.tasks.RepeatSingleGoalMaze

    def __init__(self,
                 ...
                 physics_timestep=DEFAULT_PHYSICS_TIMESTEP,
                 control_timestep=DEFAULT_CONTROL_TIMESTEP,
                 ):
        super().__init__(
            ...
            physics_timestep=physics_timestep,
            control_timestep=control_timestep
        )

It seems the physics_timestep is default to 200Hz instead of 20Hz, and control frequency is deafult to 40Hz instead of 4Hz

Is that intended?
