#include <array_ops.h>
Reverses specific dimensions of a tensor.
NOTE tf.reverse
has now changed behavior in preparation for 1.0. tf.reverse_v2
is currently an alias that will be deprecated before TF 1.0.
Given a tensor
, and a int32
tensor axis
representing the set of dimensions of tensor
to reverse. This operation reverses each dimension i
for which there exists j
s.t. axis[j] == i
.
tensor
can have up to 8 dimensions. The number of dimensions specified in axis
may be 0 or more entries. If an index is specified more than once, a InvalidArgument error is raised.
For example:
``` tensor 't' is [[[[ 0, 1, 2, 3],
[ 4, 5, 6, 7],
[ 8, 9, 10, 11]],
[[12, 13, 14, 15],
[16, 17, 18, 19],
[20, 21, 22, 23]]]]
tensor 't' shape is [1, 2, 3, 4]
'dims' is [3] or 'dims' is -1
reverse(t, dims) ==> [[[[ 3, 2, 1, 0], [ 7, 6, 5, 4], [ 11, 10, 9, 8]], [[15, 14, 13, 12], [19, 18, 17, 16], [23, 22, 21, 20]]]]
'dims' is '[1]' (or 'dims' is '[-3]')
reverse(t, dims) ==> [[[[12, 13, 14, 15], [16, 17, 18, 19], [20, 21, 22, 23] [[ 0, 1, 2, 3], [ 4, 5, 6, 7], [ 8, 9, 10, 11]]]]
'dims' is '[2]' (or 'dims' is '[-2]')
reverse(t, dims) ==> [[[[8, 9, 10, 11], [4, 5, 6, 7], [0, 1, 2, 3]] [[20, 21, 22, 23], [16, 17, 18, 19], [12, 13, 14, 15]]]] ```
