torch.Tensor.size — PyTorch 1.10.1 documentation
https://pytorch.org/docs/stable/generated/torch.Tensor.size.html
Tensor.size(dim=None) → torch.Size or int. Returns the size of the self tensor. If dim is not specified, the returned value is a torch.Size, a subclass of tuple . If dim is specified, returns an int holding the size of that dimension. Parameters. dim ( int, optional) – The dimension for which to retrieve the size. Example:

26.11.2021 · That means that for every convolution step we want an output of [1,1,10] (the purple tensor in the figure). This expansion from input to output channels is supported by additional weights. So the final tensor of our convolutional layer weights is: [3,5,5,10] (read from left to right as we are used to).

What are tig torch sizes and how do you tell?
www.practicalmachinist.com › vb › fabrication-cnc
Dec 07, 2008 · There are many sizes and I have no clue of what I have. Google so far has not been helpful. So first, my question for the Tig guru: is there a universal system used for classifying torch sizes? How do one know what it is by looking at the torch? I know there are"series" for air and water cooled torches but what do those numbers mean?
