r"""1D convolution.
This operator takes the weight as the convolution kernel
and convolves it with data to produce an output.
In the default case, where the data_layout is `NCW`
and kernel_layout is `OIW`, conv1d takes in
a data Tensor with shape `(batch_size, in_channels, width)`,
and a weight Tensor with shape `(channels, in_channels, kernel_size)`
to produce an output Tensor with the following rule:
.. math::
\mbox{out}[b, c, w] = \sum_{dw, k}
\mbox{data}[b, k, \mbox{strides}[0] * w + dw] *
\mbox{weight}[c, k, dw]
Padding and dilation are applied to data and weight respectively before the computation.
This operator accepts data layout specification.
Semantically, the operator will convert the layout to the canonical layout
(`NCW` for data and `OIW` for weight), perform the computation,
then convert to the out_layout.
Parameters
----------
data : tvm.relay.Expr
The input data to the operator.
weight : tvm.relay.Expr

Specifies the output data type for mixed precision conv2d.
Returns
