Enum TensorValue 

pub enum TensorValue {
    Tensor(Arc<Tensor>),
    View(TensorOwnedView),
}

Owned tensor value that can be compact or a lazy view.

TensorValue is the owned counterpart to TensorRead. It is suitable for storing eager results that should remain lazy until an operation actually requires compact materialized storage.

Variants

Tensor(Arc<Tensor>)

View(TensorOwnedView)

Implementations

impl TensorValue

pub fn from_tensor(tensor: Tensor) -> TensorValue

pub fn from_tensor_arc(tensor: Arc<Tensor>) -> TensorValue

pub fn as_tensor_arc(&self) -> Option<&Arc<Tensor>>

pub fn dtype(&self) -> DType

pub fn shape(&self) -> &[usize]

pub fn tensor_read(&self) -> TensorRead<'_>

pub fn to_tensor(&self) -> Result<Tensor, Error>

Materialize this tensor value into an owned compact tensor.

Compact tensor values are cloned. Lazy host views are materialized. Backend-backed views return an explicit error instead of panicking.

Examples

use tenferro_tensor::{Tensor, TensorValue};

let value = TensorValue::from_tensor(Tensor::from_vec_col_major(
    vec![2],
    vec![1.0_f64, 2.0],
).unwrap());
let tensor = value.to_tensor()?;
assert_eq!(tensor.shape(), &[2]);

pub fn transpose_view( &self, axes: impl AsRef<[usize]>, ) -> Result<TensorValue, Error>

pub fn reshape_view(&self, shape: &[usize]) -> Result<TensorValue, Error>

pub fn slice_view(&self, config: &SliceConfig) -> Result<TensorValue, Error>

pub fn broadcast_in_dim_view( &self, shape: &[usize], dims: &[usize], ) -> Result<TensorValue, Error>
