if True, re-applies the constraining bijector
to return initializations in the original domain. Otherwise, returns
initializations in the unconstrained space.
Default value: True.
init_sample_shape
sample_shape of the sampled initializations.
Default value: [].
Tensor of shape concat([init_sample_shape,
parameter.prior.batch_shape, transformed_event_shape]), where
transformed_event_shape is parameter.prior.event_shape, if
return_constrained=True, and otherwise it is
parameter.bijector.inverse_event_shape(parameteter.prior.event_shape).
