scatter_div( ref, indices, updates, use_locking=None, name=None )
Defined in tensorflow/python/ops/gen_state_ops.py
.
See the guide: Variables > Sparse Variable Updates
Divides a variable reference by sparse updates.
This operation computes
# Scalar indices ref[indices, ...] /= updates[...] # Vector indices (for each i) ref[indices[i], ...] /= updates[i, ...] # High rank indices (for each i, ..., j) ref[indices[i, ..., j], ...] /= updates[i, ..., j, ...]
This operation outputs ref
after the update is done. This makes it easier to chain operations that need to use the reset value.
Duplicate entries are handled correctly: if multiple indices
reference the same location, their contributions divide.
Requires updates.shape = indices.shape + ref.shape[1:]
.
Args:
-
ref
: A mutableTensor
. Must be one of the following types:float32
,float64
,int64
,int32
,uint8
,uint16
,int16
,int8
,complex64
,complex128
,qint8
,quint8
,qint32
,half
. Should be from aVariable
node. -
indices
: ATensor
. Must be one of the following types:int32
,int64
. A tensor of indices into the first dimension ofref
. -
updates
: ATensor
. Must have the same type asref
. A tensor of values thatref
is divided by. -
use_locking
: An optionalbool
. Defaults toFalse
. If True, the operation will be protected by a lock; otherwise the behavior is undefined, but may exhibit less contention. -
name
: A name for the operation (optional).
Returns:
Same as ref
. Returned as a convenience for operations that want to use the updated values after the update is done.
