Help protect the Great Barrier Reef with TensorFlow on Kaggle Join Challenge


Helper used to compute the gradient for RaggedTensorToVariant.

Computes the gradient for the dense_values input to the RaggedTensorToVariant op, given the variant-encoded ragged gradients of the outputs, along with the outer row-splits and the shape of the dense-values that were provided as inputs to the RaggedTensorToVariant op.

encoded_ragged_grad A Tensor of type variant. A variant Tensor containing encoded RaggedTensor gradients.
row_splits A Tensor. Must be one of the following types: int32, int64. Outermost row-splits that were used as input to the RaggedTensorToVariant op.
dense_values_shape A Tensor of type int32. Shape of the dense_values that was used as an input to the RaggedTensorToVariant op.
Tvalues A tf.DType.
name A name for the operation (optional).

A Tensor of type Tvalues.
