torch.bitwise_left_shift
torch.bitwise_left_shift(input, other, *, out=None) -> Tensor
Computes the left arithmetic shift of "input" by "other" bits. The
   input tensor must be of integral type. This operator supports
   broadcasting to a common shape and type promotion.
The operation applied is:
  \text{out}_i = \text{input}_i << \text{other}_i

Parameters:
      * input (Tensor or Scalar) -- the first input tensor
  * **other** (*Tensor** or **Scalar*) -- the second input tensor

Keyword Arguments:
      out (Tensor, optional) -- the output tensor.
Example:
  >>> torch.bitwise_left_shift(torch.tensor([-1, -2, 3], dtype=torch.int8), torch.tensor([1, 0, 3], dtype=torch.int8))
  tensor([-2, -2, 24], dtype=torch.int8)
