tf.raw_ops.ResourceScatterNdMax(
    ref, indices, updates, use_locking=True, name=None
)

ref A Tensor of type resource. A resource handle. Must be from a VarHandleOp.
indices A Tensor. Must be one of the following types: int32, int64. A Tensor. Must be one of the following types: int32, int64. A tensor of indices into ref.
updates A Tensor. A Tensor. Must have the same type as ref. A tensor of values whose element wise max is taken with ref
use_locking An optional bool. Defaults to True. An optional bool. Defaults to True. If True, the assignment will be protected by a lock; otherwise the behavior is undefined, but may exhibit less contention.
name A name for the operation (optional).
