Found an answer :
torch. addcdiv ( input ,  value=1 ,  tensor1 ,  tensor2 ,  out=None ) → Tensor
Performs the element-wise division of  tensor1  by  tensor2 , multiply the result by the scalar  value  and add it to  input
torch. add ( input ,  other ,  alpha=1 ,  out=None )
Each element of the tensor  other  is multiplied by the scalar  alpha  and added to each element of the tensor  input .
\text{out} = \text{input} + \text{alpha} \times \text{other}
