Converts dense Tensor to SparseTensor, dropping ignore_value cells.
tfp.math.dense_to_sparse(
x, ignore_value=None, name=None
)
Args |
|---|
x
|
A Tensor.
|
ignore_value
|
Entries in x equal to this value will be
absent from the return SparseTensor. If None, default value of
x dtype will be used (e.g. '' for str, 0 for int).
|
name
|
Python str prefix for ops created by this function.
|
Raises |
|---|
ValueError
|
when x's rank is None.
