tf.contrib.tpu.infeed_enqueue_tuple

Feeds multiple Tensor values into the computation as an XLA tuple.

tf.contrib.tpu.infeed_enqueue_tuple(
    inputs, shapes, layouts=[], device_ordinal=-1, name=None
)

inputs A list of Tensor objects. A list of tensors that will be provided using the infeed mechanism.
shapes A list of shapes (each a tf.TensorShape or list of ints). The shapes of each tensor in inputs.
layouts An optional list of ints. Defaults to []. A vector holding the requested layout in minor-to-major sequence for all the tuple shapes, in the order the shapes appear in the "shapes" input. The layout elements for a sub-shape can be set to -1, in which case the corresponding layout will be computed by the infeed operation.
device_ordinal An optional int. Defaults to -1. The TPU device to use. This should be -1 when the Op is running on a TPU device, and >= 0 when the Op is running on the CPU device.
name A name for the operation (optional).

The created Operation.
