torch.eq、torch.ne、torch.gt、torch.lt、torch.ge、torch.le 等函数详解

torch.eq、torch.ne、torch.gt、torch.lt、torch.ge、torch.le

以上全是简写 参数是input, other, out=None 逐元素比较input和other 返回是torch.BoolTensor

import torch

a=torch.tensor([[1, 2], [3, 4]])
b=torch.tensor([[1, 2], [4, 3]])

print(torch.eq(a,b))#equals
# tensor([[ True,  True],
#         [False, False]])

print(torch.ne(a,b))#not equal to
# tensor([[False, False],
#         [ True,  True]])

print(torch.gt(a,b))#greater than
# tensor([[False, False],
#         [False,  True]])

print(torch.lt(a,b))#less than
# tensor([[False, False],
#         [ True, False]])

print(torch.ge(a,b))#greater than or equal to
# tensor([[ True,  True],
#         [False,  True]])

print(torch.le(a,b))#less than or equal to
# tensor([[ True,  True],
#         [ True, False]])
