__init__(dtype, dim=0, choices=0, factors=1, alias=None)[source]#

Initialize the type.

Parameters:

typename – The name of the type.
alias (str | None) – The alias of the type.
dtype (ScalarValueType)
dim (int)
choices (int)
factors (int)

__new__(**kwargs)#

assignment_type()[source]#

Return the value type for assignment.

Return type:: VectorValueType

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()[source]#

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()[source]#: Return the long string representation of the type.

ndim()[source]#

Return the number of dimensions of the value type.

Return type:: int

set_parent_type(parent_type)#

Parameters:: parent_type (TypeBase)

short_str()#

Return the short string representation of the type.

Return type:: str

size()[source]#

Return the total size of the value type.

Return type:: int

size_tuple()[source]#

Return the size of the value type as a tuple.

Return type:: Tuple[int]

tensor_dtype()[source]#

Return the corresponding PyTorch tensor dtype.

Return type:: dtype
