+Renormalizes the sub-`Tensor`s along dimension `dim` such that they do not exceed norm `maxnorm`.
 
 `y = torch.renorm(x, p, dim, maxnorm)` returns a version of `x` with `p`-norms lower than `maxnorm` over non-`dim` dimensions.
 The `dim` argument is not to be confused with the argument of the same name in function [`norm`](#torch.norm).
