class, weight, bias, stride=1, padding=0, dilation=1, groups=1, padding_mode='zeros', scale=1.0, zero_point=0, dtype=torch.quint8)[source]

Applies a 1D convolution over a quantized 1D input composed of several input planes.

See Conv1d for details and output shape.

  • input – quantized input tensor of shape (minibatch,in_channels,iW)(\text{minibatch} , \text{in\_channels} , iW)

  • weight – quantized filters of shape (out_channels,in_channelsgroups,iW)(\text{out\_channels} , \frac{\text{in\_channels}}{\text{groups}} , iW)

  • biasnon-quantized bias tensor of shape (out_channels)(\text{out\_channels}). The tensor type must be torch.float.

  • stride – the stride of the convolving kernel. Can be a single number or a tuple (sW,). Default: 1

  • padding – implicit paddings on both sides of the input. Can be a single number or a tuple (padW,). Default: 0

  • dilation – the spacing between kernel elements. Can be a single number or a tuple (dW,). Default: 1

  • groups – split input into groups, in_channels\text{in\_channels} should be divisible by the number of groups. Default: 1

  • padding_mode – the padding mode to use. Only “zeros” is supported for quantized convolution at the moment. Default: “zeros”

  • scale – quantization scale for the output. Default: 1.0

  • zero_point – quantization zero_point for the output. Default: 0

  • dtype – quantization data type to use. Default: torch.quint8
