argMin
Returns the index of minimum value of each row of the input tensor in the given dimension dim.
If keepDim is true, the output tensor is of the same size as input except in the dimension dim where it is of size 1. Otherwise, dim is squeezed, resulting in the output tensor having 1 fewer dimension.
Return
the index of maximum value of each row of the input tensor in the given dimension dim.
Parameters
dim
the dimension to reduce.
keepDim
whether the output tensor has dim retained or not.
