torch.nn.functional.local_response_norm
torch.nn.functional.local_response_norm(input, size, alpha=0.0001, beta=0.75, k=1.0)
Applies local response normalization over an input signal composed
   of several input planes, where channels occupy the second
   dimension. Applies normalization across channels.
See "LocalResponseNorm" for details.
Return type:
