LayerNorm — PyTorch 1.10.1 documentation
pytorch.org › docs › stableThe mean and standard-deviation are calculated over the last D dimensions, where D is the dimension of normalized_shape.For example, if normalized_shape is (3, 5) (a 2-dimensional shape), the mean and standard-deviation are computed over the last 2 dimensions of the input (i.e. input.mean((-2,-1))).

https://stackoverflow.com/questions/59830168shouldn't the layer normalization of x = torch.tensor ( [ [1.5,0,0,0,0]]) be [ [1.5,-0.5,-0.5,-0.5]] ? according to this paper paper and the equation from the pytorch doc. But the torch.nn.LayerNorm gives [ [ 1.7320, -0.5773, -0.5773, -0.5773]] Here is the example code:
Layer Normalization in Pytorch (With Examples)
wandb.ai › wandb_fc › LayerNormImplementing Layer Normalization in PyTorch is a relatively simple task. To do so, you can use torch.nn.LayerNorm (). For convolutional neural networks however, one also needs to calculate the shape of the output activation map given the parameters used while performing convolution. A simple implementation is provided in calc_activation_shape ...
