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

# Vector indices (for each 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.
