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)
