Unsupported

[TOC]

This module includes unsupported and experimental features which are exposed but not part of the supported public API. Anything in this module can change without notice, even across a patch release.

Utilities

tf.unsupported.constant_value(tensor) {#constant_value}

Returns the constant value of the given tensor, if efficiently calculable.

This function attempts to partially evaluate the given tensor, and returns its value as a numpy ndarray if this succeeds.

TODO(mrry): Consider whether this function should use a registration mechanism like gradients and ShapeFunctions, so that it is easily extensible.

Args:
  • tensor: The Tensor to be evaluated.
Returns:

A numpy ndarray containing the constant value of the given tensor, or None if it cannot be calculated.

Raises:
  • TypeError: if tensor is not an ops.Tensor.

Other Functions and Classes

tf.unsupported.make_all(module_name) {#make_all}

Generate __all__ from a module's docstring.

Usage: make_all(__name__). The caller module must have a docstring, and __all__ will contain all symbols with @@ references.

Args:
  • module_name: The name of the module (usually __name__).
Returns:

A list suitable for use as __all__.
