Fills empty rows in the input 2-D SparseTensor
with a default value.
tf.sparse.fill_empty_rows(
sp_input, default_value, name=None
)
This op adds entries with the specified default_value
at index
[row, 0]
for any row in the input that does not already have a value.
For example, suppose sp_input
has shape [5, 6]
and non-empty values:
[0, 1]: a
[0, 3]: b
[2, 0]: c
[3, 1]: d
Rows 1 and 4 are empty, so the output will be of shape [5, 6]
with values:
[0, 1]: a
[0, 3]: b
[1, 0]: default_value
[2, 0]: c
[3, 1]: d
[4, 0]: default_value
Note that the input may have empty columns at the end, with no effect on this op.
The output SparseTensor
will be in row-major order and will have the
same shape as the input.
This op also returns an indicator vector such that
empty_row_indicator[i] = True iff row i was an empty row.
