tf.xla.experimental.compile

TensorFlow 2.0 version View source on GitHub

Builds an operator that compiles and runs computation with XLA.

Aliases:

  • tf.compat.v1.xla.experimental.compile
  • tf.compat.v2.xla.experimental.compile
tf.xla.experimental.compile(
    computation,
    inputs=None
)

NOTE: In eager mode, computation will have @tf.function semantics.

Args:

  • computation: A Python function that builds a computation to apply to the input. If the function takes n inputs, 'inputs' should be a list of n tensors.

    computation may return a list of operations and tensors. Tensors must come before operations in the returned list. The return value of compile is a list of tensors corresponding to the tensors from the output of computation.

    All Operations returned from computation will be executed when evaluating any of the returned output tensors.

  • inputs: A list of inputs or None (equivalent to an empty list). Each input can be a nested structure containing values that are convertible to tensors. Note that passing an N-dimension list of compatible values will result in a N-dimension list of scalar tensors rather than a single Rank-N tensors. If you need different behavior, convert part of inputs to tensors with tf.convert_to_tensor.

Returns:

Same data structure as if computation(*inputs) is called directly with some exceptions for correctness. Exceptions include: 1) None output: a NoOp would be returned which control-depends on computation. 2) Single value output: A tuple containing the value would be returned. 3) Operation-only outputs: a NoOp would be returned which control-depends on computation. TODO(b/121383831): Investigate into removing these special cases.

Raises:

  • RuntimeError: if called when eager execution is enabled.
