>>> m = nn.ConstantPad1d(2, 3.5) >>> input = torch.randn(1, 2, 4) >>> input tensor([[[-1.0491, -0.7152, -0.0749, 0.8530], [-1.3287, 1.8966, 0.1466, -0.2771]]]) >>> m(input) tensor([[[ 3.5000, 3.5000, -1.0491, -0.7152, -0.0749, 0.8530, 3.5000, 3.5000], [ 3.5000, 3.5000, -1.3287, 1.8966, 0.1466, -0.2771, 3.5000, 3.5000]]]) >>> m = nn.ConstantPad1d(2, 3.5) >>> input = torch.randn(1, 2, 3) >>> input tensor([[[ 1.6616, 1.4523, -1.1255], [-3.6372, 0.1182, -1.8652]]]) >>> m(input) tensor([[[ 3.5000, 3.5000, 1.6616, 1.4523, -1.1255, 3.5000, 3.5000], [ 3.5000, 3.5000, -3.6372, 0.1182, -1.8652, 3.5000, 3.5000]]]) >>> # using different paddings for different sides >>> m = nn.ConstantPad1d((3, 1), 3.5) >>> m(input) tensor([[[ 3.5000, 3.5000, 3.5000, 1.6616, 1.4523, -1.1255, 3.5000], [ 3.5000, 3.5000, 3.5000, -3.6372, 0.1182, -1.8652, 3.5000]]])
