class TensorValueTypeBase

Bases: ValueType

A value type refers to a type of some features associated with physical objects.

Methods

assignment_type()	Return the value type for assignment.
downcast_compatible(other[, ...])	Check if the type is downcast-compatible with the other type; that is, if this type is a subtype of the other type.
from_tensor(tensor)	Create a value type from a pytorch tensor.
is_intrinsically_quantized()	Return whether the value type can be quantized.
long_str()	Return the long string representation of the type.
ndim()	Return the number of dimensions of the value type.
short_str()	Return the short string representation of the type.
size()	Return the total size of the value type.
size_tuple()	Return the size of the value type as a tuple.
tensor_dtype()	Return the corresponding PyTorch tensor dtype.

Attributes

alias	An optional alias of the type.
base_typename	Return the typename of the base type.
is_list_type	Return whether the type is a list type.
is_object_type	Return whether the type is an object type.
is_pyobj_value_type	Return whether the type is a Python object value type.
is_sequence_type	Return whether the type is a sequence type.
is_tensor_value_type	Return whether the type is a tensor value type.
is_tuple_type	Return whether the type is a tuple type.
is_value_type	Return whether the type is a value type.
parent_type	The parent type of the type.
parent_typename	Return the typename of the parent type.
quantized	Whether the tensor is quantized.
typename	The (full) typename of the type.

__init__(typename, quantized, alias=None)

Initialize the type.

Parameters:

• typename (str) – The name of the type.

• alias (str | None) – The alias of the type.

• quantized (bool)

__new__(**kwargs)

assignment_type()

Return the value type for assignment.

Return type:

TypeBase

downcast_compatible(other, allow_self_list=False, allow_list=False)

Check if the type is downcast-compatible with the other type; that is, if this type is a subtype of the other type.

Parameters:

• other (TypeBase) – the other type.

• allow_self_list (bool) – if True, this type can be a list type derived from the other type.

• allow_list (bool) – if True, the other type can be a list type derived from the type.

Return type:

bool

static from_tensor(tensor)

Create a value type from a pytorch tensor.

Parameters:

tensor (Tensor) – the tensor.

Returns:

the tensor value type.

Return type:

TensorValueTypeBase

is_intrinsically_quantized()

Return whether the value type can be quantized. In this project, quantizable means we can transform the value into a single integer scalar. Therefore, only BOOL-valued and INTxx-valued tensors are quantizable.

Returns:

True if the value type can be quantized.

Return type:

bool

long_str()

Return the long string representation of the type.

Return type:

str

ndim()

Return the number of dimensions of the value type.

Return type:

int

short_str()

Return the short string representation of the type.

Return type:

str

size()

Return the total size of the value type.

Return type:

int

size_tuple()

Return the size of the value type as a tuple.

Return type:

Tuple[int]

tensor_dtype()

Return the corresponding PyTorch tensor dtype.

Return type:

dtype

property parent_type: TypeBase | None

The parent type of the type.

property parent_typename

Return the typename of the parent type.

property quantized: bool

Whether the tensor is quantized.

property typename: str

The (full) typename of the type.
