Expand description
Experimental. Represents the complete type information of a TensorFlow value.
Variants
TftUnset
The default represents an uninitialized values.
TftVar
Type variables may serve as placeholder for any other type ID in type templates.
Examples: TFT_DATASET[TFT_VAR[“T”]] is a Dataset returning a type indicated by “T”. TFT_TENSOR[TFT_VAR[“T”]] is a Tensor of n element type indicated by “T”. TFT_TENSOR[TFT_VAR[“T”]], TFT_TENSOR[TFT_VAR[“T”]] are two tensors of identical element types. TFT_TENSOR[TFT_VAR[“P”]], TFT_TENSOR[TFT_VAR[“Q”]] are two tensors of potentially different element types.
TftAny
Wildcard type. Describes a parameter of unknown type. In TensorFlow, that can mean either a “Top” type (accepts any type), or a dynamically typed object whose type is unknown in context. Important: “unknown” does not necessarily mean undeterminable!
TftProduct
The algebraic product type. This is an algebraic type that may be used just for logical grouping. Not to confused with TFT_TUPLE which describes a concrete object of several elements.
Example: TFT_DATASET[TFT_PRODUCT[TFT_TENSOR[TFT_INT32], TFT_TENSOR[TFT_FLOAT64]]] is a Dataset producing two tensors, an integer one and a float one.
TftNamed
Represents a named field, with the name stored in the attribute.
Parametrization:
TFT_NAMED[
is the type of the field is the field name, as string (thpugh can theoretically be an int as well)
Example: TFT_RECORD[ TFT_NAMED[TFT_TENSOR[TFT_INT32]]{‘foo’}, TFT_NAMED[TFT_TENSOR[TFT_FLOAT32]]{‘bar’}, ] is a structure with two fields, an int tensor “foo” and a float tensor “bar”.
TftCallable
Callable types describe functions and ops.
Parametrization:
TFT_CALLABLE[
is the type of the arguments; TFT_PRODUCT represents multiple arguments. is the return type; TFT_PRODUCT represents multiple return values (that means that callables returning multiple things don’t necessarily return a single tuple).
Example: TFT_CALLABLE[ TFT_ANY, TFT_PRODUCT[TFT_TENSOR[TFT_INT32], TFT_TENSOR[TFT_FLOAT64]], ] is a callable with unspecified (for now) input arguments, and two return values of type tensor.
TftTensor
The usual Tensor. This is a parametric type.
Parametrization:
TFT_TENSOR[
is currently limited to one of the element types defined below. is not yet defined, and may only be TFT_UNKNOWN for now.
A TFT_SHAPE type will be defined in the future.
Example: TFT_TENSOR[TFT_INT32, TFT_UNKNOWN] is a Tensor of int32 element type and unknown shape.
TODO(mdan): Define TFT_SHAPE and add more examples.
TftArray
Array (or tensorflow::TensorList in the variant type registry).
Note: this is not to be confused with the deprecated TensorArray*
ops
which are not supported by FullType.
This type represents a random-access list whose elements can be
described by a single type. Although immutable, Array is expected to
support efficient mutation semantics (i.e. element update) in the
user-facing API.
The element type may be generic or even TFT_ANY for a heterogenous list.
Parametrization:
TFT_ARRAY[
may be any concrete type.
Examples: TFT_ARRAY[TFT_TENSOR[TFT_INT32]] is a TensorArray holding int32 Tensors of any shape. TFT_ARRAY[TFT_TENSOR[TFT_UNKNOWN]] is a TensorArray holding Tensors of mixed element types. TFT_ARRAY[TFT_UNKNOWN] is a TensorArray holding any element type. TFT_ARRAY[] is equivalent to TFT_ARRAY[TFT_UNKNOWN]. TFT_ARRAY[TFT_ARRAY[]] is an array or arrays (of unknown types).
TftOptional
Optional (or tensorflow::OptionalVariant in the variant type registry). This type represents a value that may either hold an element of a single specified type, or nothing at all.
Parametrization:
TFT_OPTIONAL[
may be any concrete type.
Examples: TFT_OPTIONAL[TFT_TENSOR[TFT_INT32]] is an Optional holding an int32 Tensor of any shape.
TftLiteral
Literal types describe compile-time constant values. Literal types may also participate in dependent types.
Parametrization:
TFT_LITERAL[
may be any concrete type compatible that can hold is the type’s attribute, and holds the actual literal value
Examples: TFT_LITERAL[TFT_INT32]{1} is the compile-time constant 1.
TftDataset
Datasets created by tf.data ops and APIs. Datasets have generator/iterable semantics, that is, one can construct an iterator from them. Like Array, they are considered to return elements that can be described by a single type. Unlike Array, they do not support random access or mutation, and can potentially produce an infinite number of elements. A datasets can produce logical structures (e.g. multiple elements). This is expressed using TFT_PRODUCT.
Parametrization: TFT_ARRAY[
may be a concrete type or a type symbol. It represents the data type of the elements produced by the dataset.
Examples: TFT_DATSET[TFT_TENSOR[TFT_INT32]] is a Dataset producing single int32 Tensors of unknown shape. TFT_DATSET[TFT_PRODUCT[TFT_TENSOR[TFT_INT32], TFT_TENSOR[TFT_FLOAT32]] is a Dataset producing pairs of Tensors, one integer and one float. Note: The high ID number is to prepare for the eventuality that Datasets will be supported by user types in the future.
TftMutexLock
A mutex lock tensor, produced by tf.raw_ops.MutexLock. Unlike strict execution models, where ownership of a lock is denoted by “running after the lock has been acquired”, in non-strict mode, lock ownership is in the true sense: “the op argument representing the lock is available”. Mutex locks are the dynamic counterpart of control dependencies. TODO(mdan): Properly document this thing.
Parametrization: TFT_MUTEX_LOCK[].
TftBool
The bool element type. TODO(mdan): Quantized types, legacy representations (e.g. ref)
TftUint8
Integer element types.
TftUint16
TftUint32
TftUint64
TftInt8
TftInt16
TftInt32
TftInt64
TftHalf
Floating-point element types.
TftFloat
TftDouble
TftBfloat16
TftComplex64
Complex element types. TODO(mdan): Represent as TFT_COMPLEX[TFT_DOUBLE] instead?
TftComplex128
TftString
The string element type.
