Attributes
inner_results	Results of the inner kernel.
max_trajectory_length	Floating point scalar Tensor. Maximum HMC trajectory length.
step	Int32 scalar Tensor. The number of steps this kernel has taken. Increases by 1 for every call to one_step.
adaptation_rate	Floating point scalar Tensor. How rapidly to adapt the trajectory length.
jitter_amount	Floating point scalar Tensor. How much to jitter the trajectory on the next step. The trajectory length is sampled from [(1 - jitter_amount) * max_trajectory_length, max_trajectory_length].
averaged_sq_grad	Floating point scalar Tensor. Moving average of squared criterion gradients.
averaged_sq_grad_adaptation_rate	Floating point scalar Tensor. How rapidly to adapt the running average squared gradient. This is 1 - beta_2 from Adam.
averaged_max_trajectory_length	Floating point scalar Tensor. Moving average of the maximum of trajectory length. This is used after the burnin period.
criterion	Floating point Tensor with shape [C0, ..., Cb] with b > 0. The value of the criterion returned by the criterion_fn corresponding to each Markov chain.
seed	PRNG seed; see tfp.random.sanitize_seed for details. The random seed used by the kernel in the previous step.
