ReshapeLayer

ReshapeLayer[dims]

represents a net layer that reinterprets the input to be an array of dimensions dims.

Details and Options

  • The total number of elements in the input array must equal the total number of elements in the output array.
  • ReshapeLayer[…][input] explicitly computes the output from applying the layer to input.
  • ReshapeLayer[…][{input1,input2,…}] explicitly computes outputs for each of the inputi.
  • ReshapeLayer exposes the following ports for use in NetGraph etc.:
  • "Input"a tensor of arbitrary rank
    "Output"a tensor of dimension dims
  • ReshapeLayer is typically used inside NetChain, NetGraph, etc.
  • ReshapeLayer normally infers the dimensions of its input from its context in NetChain etc. To specify the dimensions explicitly as {n1,n2,…}, use ReshapeLayer["Input"->{n1,n2,…}].
