tf.compat.v1.raw_ops.CollectivePermute
tf.raw_ops.CollectivePermute(
input, source_target_pairs, name=None
)
Each instance supplies its own input.
For example, suppose there are 4 TPU instances: [A, B, C, D]
. Passing
source_target_pairs=[[0,1],[1,2],[2,3],[3,0]]
gets the outputs:
[D, A, B, C]
.
Args |
input
|
A Tensor . Must be one of the following types: float32 , float64 , int32 , uint8 , int16 , int8 , complex64 , int64 , qint8 , quint8 , qint32 , bfloat16 , qint16 , quint16 , uint16 , complex128 , half , uint32 , uint64 .
The local input to be permuted. Currently only supports float and
bfloat16.
|
source_target_pairs
|
A Tensor of type int32 .
A tensor with shape [num_pairs, 2].
|
name
|
A name for the operation (optional).
|
Returns |
A Tensor . Has the same type as input .
