WebIn torchscript mode padding as single int is not supported, use a sequence of length 1: [padding, ]. fill ( number or tuple) – Pixel fill value for constant fill. Default is 0. If a tuple of length 3, it is used to fill R, G, B channels respectively. This value is only used when the padding_mode is constant. Webpad_sequence stacks a list of Tensors along a new dimension, and pads them to equal length. For example, if the input is list of sequences with size L x * and if batch_first is false, and T x B x * otherwise. B is batch size. It is equal to the number of elements in sequences. T is length of the longest sequence.
