Methods

impl Tensor

pub unsafe fn uninitialized<T: Datum>(shape: &[usize]) -> TractResult<Tensor>

Create an uninitialized tensor (dt as type paramater).

pub unsafe fn uninitialized_dt(
    dt: DatumType,
    shape: &[usize]
) -> TractResult<Tensor>

Create an uninitialized tensor (dt as regular parameter).

pub unsafe fn uninitialized_aligned<T: Datum>(
    shape: &[usize],
    alignment: usize
) -> TractResult<Tensor>

Create an uninitialized tensor with a given alignment (in bytes).

pub unsafe fn uninitialized_aligned_dt(
    dt: DatumType,
    shape: &[usize],
    alignment: usize
) -> TractResult<Tensor>

Create an uninitialized tensor with a given alignment (in bytes).

pub unsafe fn from_raw<T: Datum>(
    shape: &[usize],
    content: &[u8]
) -> TractResult<Tensor>

Create an tensor from raw data.

It copies the data, aligning it to the size of T.

pub unsafe fn from_raw_dt(
    dt: DatumType,
    shape: &[usize],
    content: &[u8]
) -> TractResult<Tensor>

pub unsafe fn null<T: Datum>(shape: &[usize]) -> TractResult<Tensor>

Creates a null tensor (this is rare, and should stay that way).

pub unsafe fn null_dt(dt: DatumType, shape: &[usize]) -> TractResult<Tensor>

Creates a null tensor (this is rare, and should stay that way).

pub fn is_null(&self) -> bool

Check weather self is a null tensor.

pub fn rank(&self) -> usize

Get the number of dimensions (or axes) of the tensor.

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

Get the shape of the tensor.

pub fn len(&self) -> usize

Get the number of valeus in the tensor.

pub unsafe fn into_shape(self, shape: &[usize]) -> TractResult<Tensor>

Reshape the tensor to shape.

pub fn datum_type(&self) -> DatumType

Get the datum type of the tensor.

pub fn dump_t<D: Datum>(&self, force_full: bool) -> TractResult<String>

Dump the tensor in a human readable form.

force_full will force the tensor to be dump in full even if it is big.

pub fn dump(&self, force_full: bool) -> TractResult<String>

Dump the tensor in a human readable form.

force_full will force the tensor to be dump in full even if it is big.

pub fn l1(&self, other: &Self) -> TractResult<f64>

Compute a normalized L1 distance between two tensors.

pub fn close_enough(&self, other: &Self, approx: bool) -> TractResult<()>

Compare two tensors, allowing for rounding errors.

pub fn into_array<D: Datum>(self) -> TractResult<ArrayD<D>>

Transform the tensor into a ndarray::Array.

pub fn to_array_view<'a, D: Datum>(&'a self) -> TractResult<ArrayViewD<'a, D>>

Transform the data as a ndarray::Array.

pub fn to_array_view_mut<'a, D: Datum>(
    &'a mut self
) -> TractResult<ArrayViewMutD<'a, D>>

Transform the data as a mutable ndarray::Array.

pub fn as_ptr<D: Datum>(&self) -> TractResult<*const D>

Access the data as a pointer.

pub fn as_ptr_mut<D: Datum>(&mut self) -> TractResult<*mut D>

Access the data as a mutable pointer.

pub fn as_slice<D: Datum>(&self) -> TractResult<&[D]>

Access the data as a slice.

pub fn as_slice_mut<D: Datum>(&mut self) -> TractResult<&mut [D]>

Access the data as a mutable slice.

pub fn to_scalar<'a, D: Datum>(&'a self) -> TractResult<&D>

Access the data as a scalar.

pub fn cast_to<D: Datum>(&self) -> TractResult<Cow<Tensor>>

Optionnaly convert data to a tensor for a new DatumType.

pub fn cast_to_dt(&self, dt: DatumType) -> TractResult<Cow<Tensor>>

Optionnaly convert data to a tensor for a new DatumType.

pub fn cast_to_scalar<D: Datum + Copy>(&self) -> TractResult<D>

Access the data as a scalar, after a cast.

pub fn deep_clone(&self) -> Tensor
