tf.unravel_index

Converts an array of flat indices into a tuple of coordinate arrays.

tf.unravel_index(
    indices, dims, name=None
)

Example:

y = tf.unravel_index(indices=[2, 5, 7], dims=[3, 3])
# 'dims' represent a hypothetical (3, 3) tensor of indices:
# [[0, 1, *2*],
#  [3, 4, *5*],
#  [6, *7*, 8]]
# For each entry from 'indices', this operation returns
# its coordinates (marked with '*'), such as
# 2 ==> (0, 2)
# 5 ==> (1, 2)
# 7 ==> (2, 1)
y ==> [[0, 1, 2], [2, 2, 1]]

Args:

Returns:

A Tensor. Has the same type as indices.
