tf.sparse.retain(
sp_input, to_retain
)
For example, if sp_input has shape [4, 5] and 4 non-empty string values:
[0, 1]: a
[0, 3]: b
[2, 0]: c
[3, 1]: d
and to_retain = [True, False, False, True], then the output will be a SparseTensor of shape [4, 5] with 2 non-empty values:
[0, 1]: a
[3, 1]: d
| Args | |
|---|---|
| sp_input | The input SparseTensor with N non-empty elements. |
| to_retain | A bool vector of length N with M true values. |
| Returns |
|---|
| A SparseTensor with the same shape as the input and M non-empty elements corresponding to the true positions in to_retain. |
| Raises | |
|---|---|
| TypeError | If sp_input is not a SparseTensor. |
