tf.raw_ops.LMDBDataset
Stay organized with collections
Save and categorize content based on your preferences.
Creates a dataset that emits the key-value pairs in one or more LMDB files.
tf.raw_ops.LMDBDataset(
filenames, output_types, output_shapes, name=None
)
The Lightning Memory-Mapped Database Manager, or LMDB, is an embedded binary
key-value database. This dataset can read the contents of LMDB database files,
the names of which generally have the .mdb
suffix.
Each output element consists of a key-value pair represented as a pair of
scalar string Tensor
s, where the first Tensor
contains the key and the
second Tensor
contains the value.
LMDB uses different file formats on big- and little-endian machines.
LMDBDataset
can only read files in the format of the host machine.
