mlr_pipeops_torch_ingress function

Entrypoint to Torch Network

Use this as entry-point to mlr3torch-networks. Unless you are an advanced user, you should not need to use this directly but PipeOpTorchIngressNumeric, PipeOpTorchIngressCategorical or PipeOpTorchIngressLazyTensor.

Parameters

Defined by the construction argument param_set.

Input and Output Channels

One input channel called "input" and one output channel called "output". For an explanation see PipeOpTorch.

State

The state is set to the input shape.

Internals

Creates an object of class TorchIngressToken for the given task. The purpuse of this is to store the information on how to construct the torch dataloader from the task for this entry point of the network.
