Working with sparse tensors

Only elements not equal to zero will be present in the result. The resultingSparseTensor has the same dtype and shape as the input.

sp = tf.sparse.from_dense([0, 0, 3, 0, 1]) sp.shape.as_list() [5] sp.values.numpy() array([3, 1], dtype=int32) sp.indices.numpy() array([[2], [4]])

Args
tensor	A dense Tensor to be converted to a SparseTensor.
name	Optional name for the op.

Returns
The SparseTensor.
