torch.result_type

torch.result_type(tensor1, tensor2) → dtype

Returns the torch.dtype that would result from performing an arithmetic operation on the provided input tensors. See type promotion documentation for more information on the type promotion logic.

Parameters
  • tensor1 (Tensor or Number) – an input tensor or number
  • tensor2 (Tensor or Number) – an input tensor or number

Example:

>>> torch.result_type(torch.tensor([1, 2], dtype=torch.int), 1.0)
torch.float32
>>> torch.result_type(torch.tensor([1, 2], dtype=torch.uint8), torch.tensor(1))
torch.uint8
