Notes:

This API is ONLY available in Dygraph mode

System Message: WARNING/2 (/usr/local/lib/python3.8/site-packages/paddle/fluid/dygraph/tensor_patch_methods.py:docstring of paddle.fluid.dygraph.tensor_patch_methods.monkey_patch_tensor.<locals>.to_dense, line 3)

Definition list ends without a blank line; unexpected unindent.

Convert the current SparseTensor(COO or CSR) to DenseTensor.

Returns

A DenseTensor

Return type

Tensor
