tensorflow (version 2.2.0)

tf_function: Creates a callable TensorFlow graph from an R function.

Description

tf_function constructs a callable that executes a TensorFlow graph created by tracing the TensorFlow operations in f. This allows the TensorFlow runtime to apply optimizations and exploit parallelism in the computation defined by f.

Usage

tf_function(
  f,
  input_signature = NULL,
  autograph = FALSE,
  experimental_autograph_options = NULL
)

Arguments

f

the function to be compiled

input_signature

A possibly nested sequence of tf$TensorSpec objects specifying the shapes and dtypes of the tensors that will be supplied to this function. If NULL, a separate function is instantiated for each inferred input signature. If input_signature is specified, every input to f must be a tensor.

autograph

Whether autograph should be applied on f before tracing a graph. This allows for dynamic control flow (if's, loops etc.) in the traced graph. See https://www.tensorflow.org/guide/autograph for more information. Note: We set the default to FALSE until this functionality is available from R.

experimental_autograph_options

Experimental knobs (in the form of a tuple of tf$autograph$Feature values) to control behavior when autograph = TRUE.
