Generating a learning rate schedule for PPOConfig

Question

I am using Ray's PPO algorithm, and see in PPOConfig that the training() function accepts a learning rate schedule as lr_schedule:

From the Docs:

Args:
            lr_schedule: Learning rate schedule. In the format of
                [[timestep, lr-value], [timestep, lr-value], ...]
                Intermediary timesteps will be assigned to interpolated learning rate
                values. A schedule should normally start from timestep 0.

Is there a readily accessible function I can use to generate the schedule? I am using Ray with PyToch, in case that helps.

Ray version: 2.9.3
