T3Variations.zeros#

static t3toolbox.frame_variations_format.T3Variations.zeros(variation_shapes, stack_shape=(), use_jax=False)#

def zeros(
        variation_shapes,                           # (tucker_variation_shapes, tt_variation_shapes)
        stack_shape:    typ.Tuple[int, ...] = (),   # full leading stack K + C
        use_jax:        bool = False,
) -> 'T3Variations':

Zero variations of the given structure (additive identity).

variation_shapes = (tucker_variation_shapes, tt_variation_shapes) – e.g. a frame’s T3Frame.variation_shapes. (See zeros_like() to take the structure from an object.)

Parameters:

stack_shape (t3toolbox.backend.common.typ.Tuple[int, Ellipsis])
use_jax (bool)

Return type:

T3Variations
