tf.compat.v1.raw_ops.ResourceScatterSub

tf.raw_ops.ResourceScatterSub(
    resource, indices, updates, 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, ...]

Duplicate entries are handled correctly: if multiple indices reference the same location, their contributions add.

Requires updates.shape = indices.shape + ref.shape[1:] or updates.shape = [].

Args
resource	A Tensor of type resource. 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 be one of the following types: float32, float64, int32, uint8, int16, int8, complex64, int64, qint8, quint8, qint32, bfloat16, uint16, complex128, half, uint32, uint64. A tensor of updated values to add to ref.
name	A name for the operation (optional).

Returns
The created Operation.
