tf.TensorSpec

Describes a tf.Tensor.

Inherits From: TypeSpec

Metadata for describing the tf.Tensor objects accepted or returned by some TensorFlow APIs.

shape Value convertible to tf.TensorShape. The shape of the tensor.
dtype Value convertible to tf.DType. The type of the tensor values.
name Optional name for the Tensor.

TypeError If shape is not convertible to a tf.TensorShape, or dtype is not convertible to a tf.DType.

dtype Returns the dtype of elements in the tensor.
name Returns the (optionally provided) name of the described tensor.
shape Returns the TensorShape that represents the shape of the tensor.
value_type The Python type for values that are compatible with this TypeSpec.

Methods

from_spec

View source

Returns a TensorSpec with the same shape and dtype as spec.

spec = tf.TensorSpec(shape=[8, 3], dtype=tf.int32, name="OriginalName")
tf.TensorSpec.from_spec(spec, "NewName")
TensorSpec(shape=(8, 3), dtype=tf.int32, name='NewName')

Args
spec The TypeSpec used to create the new TensorSpec.
name The name for the new TensorSpec. Defaults to spec.name.

from_tensor

View source

Returns a TensorSpec that describes tensor.

tf.TensorSpec.from_tensor(tf.constant([1, 2, 3]))
TensorSpec(shape=(3,), dtype=tf.int32, name=None)

Args
tensor The tf.Tensor that should be described.
name A name for the TensorSpec. Defaults to tensor.op.name.

Returns
A TensorSpec that describes tensor.

is_compatible_with

View source

Returns True if spec_or_tensor is compatible with this TensorSpec.

Two tensors are considered compatible if they have the same dtype and their shapes are compatible (see tf.TensorShape.is_compatible_with).

Args
spec_or_tensor A tf.TensorSpec or a tf.Tensor

Returns
True if spec_or_tensor is compatible with self.

most_specific_compatible_type

View source

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.

__eq__

View source

Return self==value.

__ne__

View source

Return self!=value.
