# tf.contrib.data.prefetch_to_device

tf.contrib.data.prefetch_to_device(
device,
buffer_size=None
)


A transformation that prefetches dataset values to the given device.

NOTE: Although the transformation creates a tf.data.Dataset, the transformation must be the final Dataset in the input pipeline.

#### Args:

• device: A string. The name of a device to which elements will be prefetched.
• buffer_size: (Optional.) The number of elements to buffer on device. Defaults to an automatically chosen value.

#### Returns:

A Dataset transformation function, which can be passed to tf.data.Dataset.apply.
