Divides a variable reference by sparse updates.
tf.compat.v1.scatter_div(
ref, indices, updates, use_locking=False, name=None
)
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:] or updates.shape = [].
| Args | |
|---|---|
| ref | A mutable Tensor. Must be one of the following types: float32,float64, int32, uint8, int16, int8, complex64, int64,qint8, quint8, qint32, bfloat16, uint16, complex128, half,uint32, uint64. Should be from a Variable node. |
| indices | A Tensor. Must be one of the following types: int32, int64. A tensor of indices into the first dimension of ref. |
| updates | A Tensor. Must have the same type as ref. A tensor of values that ref is divided by. |
| use_locking | An optional bool. Defaults to False. 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 |
|---|
| A mutable Tensor. Has the same type as ref. |
