如何将 Conv1d 转换为 Conv2d？ [PyTorch]

Question

Is it possible with PyTorch to use Conv2d to perform a Conv1d ? The question may seem weird, but I need to use a tool that is not compatible with conv1d , but it works with conv2d .

What if I have Conv1d(in,out, kernel_size=3, stride=stride, padding=1, bias=False) ? May unsqueeze help me?

I have the same problem with AvgPool1d (-> AvgPool2d) and MaxPool1d (-> MaxPool2d) .

Answer 1

A Conv2D is mostly a generalized version of Conv1D. You can of course use a degenerate version of Conv2D to reproduce a 1D convolution - You'll need to add in another dimension to the data:

data_pnt = data_pnt [..., numpy.newaxis]

You'll also need to specify the kernel size - You'll be choosing a 1D kernel - for example:

Conv2d(in,out, kernel_size=(3,1), <Other Parameters>)
