Expand description

A batch of rollout data ready for the learner.

All vectors are flat (row-major). For example, observations has length n_steps * n_envs * obs_dim, laid out as [step0_env0, step0_env1, ..., step1_env0, ...].

Fields§

§observations: Vec<f32>

§rewards: Vec<f64>

Rewards: [n_steps * n_envs].

§dones: Vec<f64>

Done flags (0.0 or 1.0): [n_steps * n_envs].

§log_probs: Vec<f64>

Log-probabilities of the collected actions: [n_steps * n_envs].

§values: Vec<f64>
