Description
🐛 Describe the bug
torch.Tensor has some faulty type annotations with respect to boolean operations.
import torch
from typing import assert_type
x = torch.tensor([0b0011])
assert_type(0b0101 & x, torch.Tensor) # false positive
assert_type(x | (0+1j), torch.Tensor) # false negative$ mypy tmp.py
tmp.py:5:1: error: Expression is of type "Any", not "Tensor" [assert-type]
tmp.py:5:22: error: Unsupported operand types for & ("int" and "Tensor") [operator]
