Mean of a tensor, alongside the specified axis.

k_mean(x, axis = NULL, keepdims = FALSE)



A tensor or variable.


A list of axes to compute the mean over (axis indexes are 1-based).


A boolean, whether to keep the dimensions or not. If keepdims is FALSE, the rank of the tensor is reduced by 1 for each entry in axis. If keep_dims is TRUE, the reduced dimensions are retained with length 1.


A tensor with the mean of elements of x.
