Implementations§

Source§

impl<B, I, O> DataLoaderBuilder<B, I, O>
where B: Backend, I: Send + Sync + Clone + Debug + 'static, O: Send + Clone + Debug + 'static,

Source

pub fn new<Bt>(batcher: Bt) -> Self
where Bt: Batcher<B, I, O> + 'static,

Creates a new data loader builder.

§Arguments
  • batcher - The batcher.
§Returns

The data loader builder.

Source

pub fn batch_size(self, batch_size: usize) -> Self

Sets the batch size to a fix number.The fix batch strategy will be used.

§Arguments
  • batch_size - The batch size.
§Returns

The data loader builder.

Source

pub fn shuffle(self, seed: u64) -> Self

Sets the seed for shuffling.

Each time the dataloader starts a new iteration, the dataset will be shuffled.

§Arguments
  • seed - The seed.
§Returns

The data loader builder.

Source

pub fn num_workers(self, num_workers: usize) -> Self

Sets the number of workers.

§Arguments
  • num_workers - The number of workers.
§Returns

The data loader builder.

Source

pub fn set_device(self, device: B::Device) -> Self

Sets the data loader device.

§Arguments
  • device - The device to use when loading a batch.
§Returns

The data loader builder.

Source

pub fn build<D>(self, dataset: D) -> Arc<dyn DataLoader<B, O>>
where D: Dataset<I> + 'static,

Builds the data loader.

§Arguments
  • dataset - The dataset.
§Returns

The data loader.
