Applies a sparse gradient to a given accumulator.
tf.raw_ops.SparseAccumulatorApplyGradient( handle, local_step, gradient_indices, gradient_values, gradient_shape, has_known_shape, name=None )
Does not add if local_step is smaller than the accumulator's global_step.
Args | |
---|---|
handle | A Tensor of type mutable string . The handle to a accumulator. |
local_step | A Tensor of type int64 . The local_step value at which the sparse gradient was computed. |
gradient_indices | A Tensor of type int64 . Indices of the sparse gradient to be accumulated. Must be a vector. |
gradient_values | 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 . Values are the non-zero slices of the gradient, and must have the same first dimension as indices, i.e., the nnz represented by indices and values must be consistent. |
gradient_shape | A Tensor of type int64 . Shape of the sparse gradient to be accumulated. |
has_known_shape | A bool . Boolean indicating whether gradient_shape is unknown, in which case the input is ignored during validation. |
name | A name for the operation (optional). |
Returns | |
---|---|
The created Operation. |
