Masks elements of `IndexedSlices`

.

tf.sparse.mask( a, mask_indices, name=None )

Given an `IndexedSlices`

instance `a`

, returns another `IndexedSlices`

that contains a subset of the slices of `a`

. Only the slices at indices not specified in `mask_indices`

are returned.

This is useful when you need to extract a subset of slices in an `IndexedSlices`

object.

# `a` contains slices at indices [12, 26, 37, 45] from a large tensor # with shape [1000, 10] a.indices # [12, 26, 37, 45] tf.shape(a.values) # [4, 10] # `b` will be the subset of `a` slices at its second and third indices, so # we want to mask its first and last indices (which are at absolute # indices 12, 45) b = tf.sparse.mask(a, [12, 45]) b.indices # [26, 37] tf.shape(b.values) # [2, 10]
