""" """
Converts a sparse tensor into dense. Converts a sparse tensor into dense.
In Python, for the ease of use, three tensors are collected into a SparseTensor class.
MindSpore uses three independent dense tensors: indices, value and dense shape to represent the sparse tensor.
Separate indexes, values and dense shape tensors can be wrapped in a Sparse Tensor object
before being passed to the OPS below.
Inputs: Inputs:
- **sparse_tensor** (:class:`mindspore.SparseTensor`): the sparse tensor to convert. - **sparse_tensor** (:class:`mindspore.SparseTensor`): the sparse tensor to convert.
