tf.TypeSpec

View source on GitHub

Specifies a TensorFlow value type.

A tf.TypeSpec provides metadata describing an object accepted or returned by TensorFlow APIs. Concrete subclasses, such as tf.TensorSpec and tf.RaggedTensorSpec, are used to describe different value types.

For example, tf.function's input_signature argument accepts a list (or nested structure) of TypeSpecs.

Creating new subclasses of TypeSpec (outside of TensorFlow core) is not currently supported. In particular, we may make breaking changes to the private methods and properties defined by this base class.

Attributes:

• value_type: The Python type for values that are compatible with this TypeSpec.

Methods

__eq__

__eq__(
    other
)

Return self==value.

__ne__

__ne__(
    other
)

Return self!=value.

is_compatible_with

View source

is_compatible_with(
    spec_or_value
)

Returns true if spec_or_value is compatible with this TypeSpec.

most_specific_compatible_type

View source

most_specific_compatible_type(
    other
)

Returns the most specific TypeSpec compatible with self and other.

Args:

• other: A TypeSpec.

Raises:

• ValueError: If there is no TypeSpec that is compatible with both self and other.
