tf.raw_ops.Reverse
Reverses specific dimensions of a tensor.
tf.raw_ops.Reverse( tensor, dims, name=None )
Given a tensor
, and a bool
tensor dims
representing the dimensions of tensor
, this operation reverses each dimension i of tensor
where dims[i]
is True
.
tensor
can have up to 8 dimensions. The number of dimensions of tensor
must equal the number of elements in dims
. In other words:
rank(tensor) = size(dims)
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 [False, False, False, True] 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 [False, True, False, False] 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 [False, False, True, False] 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]]]]
