Configuration for parsing a variable-length input feature into a Tensor
.
tf.io.FixedLenSequenceFeature(
shape, dtype, allow_missing=False, default_value=None
)
The resulting Tensor
of parsing a single SequenceExample
or Example
has
a static shape
of [None] + shape
and the specified dtype
.
The resulting Tensor
of parsing a batch_size
many Example
s has
a static shape
of [batch_size, None] + shape
and the specified dtype
.
The entries in the batch
from different Examples
will be padded with
default_value
to the maximum length present in the batch
.
To treat a sparse input as dense, provide allow_missing=True
; otherwise,
the parse functions will fail on any examples missing this feature.
