Reverses specific dimensions of a tensor.

tf.reverse( tensor, axis, name=None )

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.
