Struct TensorDataset 

Source
pub struct TensorDataset<T>
where T: Element,
{ /* private fields */ }
Expand description

tensor(先頭軸=サンプル軸)1 本からなるデータセット(PyTorch torch.utils.data.TensorDataset の単一テンソル版)。

Implementations§

Source§

impl<T> TensorDataset<T>
where T: Element,

Source

pub fn new(tensor: Tensor<T>) -> Result<TensorDataset<T>, DataError>

tensor の先頭軸をサンプル軸とみなして構築する。tensor が rank 0(スカラー。サンプル軸を持てない)のとき DataError::ScalarTensor を返す。

Source

pub fn tensor(&self) -> &Tensor<T>

保持するテンソルへの参照。

Source

pub fn get(&self, index: usize) -> Result<Tensor<T>, DataError>

index 番目のサンプル 1 件を、先頭軸を潰した shape(shape[1..]) で返す(PyTorch __getitem__ 相当)。

Trait Implementations§

impl<T> Dataset for TensorDataset<T>
where T: Element,

Source§

type Batch = Tensor<T>

Self::batch が返すバッチの型(TensorDataset<T> なら Tensor<T>、タプルなら成分ごとの Batch のタプル)。
Source§

fn len(&self) -> usize

サンプル総数。
Source§

fn batch( &self, indices: &[usize], ) -> Result<<TensorDataset<T> as Dataset>::Batch, DataError>

Source§

fn validate(&self) -> Result<(), DataError>
