  Args:
    key : PRNG key to be passed to ``generator`` function.
    shape : tuple specifying the shape of the array to be generated.
    dtype : dtype of the array to be generated.
    indices_dtype: dtype of the BCOO indices.
    nse : number of specified elements in the matrix, or if 0 < nse < 1, a
      fraction of sparse dimensions to be specified (default: 0.2).
    n_batch : number of batch dimensions. must satisfy ``n_batch >= 0`` and
      ``n_batch + n_dense <= len(shape)``.
    n_dense : number of batch dimensions. must satisfy ``n_dense >= 0`` and
      ``n_batch + n_dense <= len(shape)``.
    unique_indices : boolean specifying whether indices should be unique
      (default: True).
    sorted_indices : boolean specifying whether indices should be row-sorted in
      lexicographical order (default: False).
    generator : function for generating random values accepting a key, shape,
      and dtype. It defaults to :func:`jax.random.uniform`, and may be any
      function with a similar signature.
    **kwds : additional keyword arguments to pass to ``generator``.

  Returns:
    arr : a sparse.BCOO array with the specified properties.
