def createHandle(): Output

Creates a VARIANT scalar tensor representing this dataset.
Creates a VARIANT scalar tensor representing this dataset. This function adds ops to the current graph, that create the dataset resource.

def createInitializableIterator(sharedName: String = "", name: String = "InitializableIterator"): InitializableIterator[T, O, D, S]

Creates an Iterator for enumerating the elements of this dataset.
Creates an Iterator for enumerating the elements of this dataset.
**Note:** The returned iterator will be in an uninitialized state. You must execute the InitializableIterator.initializer op before using it.
sharedName
If non-empty, then the constructed reader will be shared under the the provided name across multiple sessions that share the same devices (e.g., when using a remote server).
name
Name for the op created in relation to the iterator.
returns
Created iterator.

def shard(numShards: Long, shardIndex: Long): Dataset[T, O, D, S]

Creates a dataset that includes only 1 / numShards of the elements of this dataset.
Creates a dataset that includes only 1 / numShards of the elements of this dataset.
This operator is very useful when running distributed training, as it allows each worker to read a unique subset of the dataset.
When reading a single input file, you can skip elements as follows:
```
tf.data.TFRecordDataset(inputFile)
  .shard(numWorkers, workerIndex)
  .repeat(numEpochs)
  .shuffle(shuffleBufferSize)
  .map(parserFn, numParallelCalls)
```
Important caveats:
- Be sure to shard before you use any randomizing operator (such as shuffle).
- Generally it is best if the shard operator is used early in the dataset pipeline. For example, when reading from a set of TensorFlow record files, shard before converting the dataset to input samples. This avoids reading every file on every worker. The following is an example of an efficient sharding strategy within a complete pipeline:
```
tf.data.listFiles(pattern)
  .shard(numWorkers, workerIndex)
  .repeat(numEpochs)
  .shuffle(shuffleBufferSize)
  .repeat()
  .interleave(tf.data.TFRecordDataset, cycleLength = numReaders, blockLength = 1)
  .map(parserFn, numParallelCalls)
```
numShards
Number of shards to use.
shardIndex
Index of the shard to obtain.
returns
Created (sharded) dataset.
