我在python中有两个计数器:counter1和counter2。当我尝试对它们执行np.nansum时,将忽略其中一个字段,因为它包含零(如果我将值更改为非零,则代码可以正常工作)。是否有任何解决方法可将所有输入键输入到输出字典中?
counter1 = Counter({'sensitivity': 1.0, 'dice': 1.0, 'specificity': 1.0, 'precision': 1.0, 'c-factor': 0.0})
counter2 = Counter({'sensitivity': 1.0, 'dice': 1.0, 'specificity': 1.0, 'precision': 1.0, 'c-factor': 0.0})
c = np.nansum([counter1, counter2])
我得到的结果是:
c= Counter({'sensitivity': 2.0, 'specificity': 2.0, 'dice': 2.0, 'precision': 2.0})
比较,当我这样做:
counter1 = Counter({'sensitivity': 1.0, 'dice': 1.0, 'specificity': 1.0, 'precision': 1.0, 'c-factor': 0.1})
counter2 = Counter({'sensitivity': 1.0, 'dice': 1.0, 'specificity': 1.0, 'precision': 1.0, 'c-factor': 0.1})
c = np.nansum([counter1, counter2])
我得到:
c=Counter({'sensitivity': 2.0, 'specificity': 2.0, 'dice': 2.0, 'precision': 2.0, 'c-factor': 0.2})
答案 0 :(得分:1)
请参见this post。如果您想保留零,则需要update
。尝试做:
c=np.nansum(counter1).copy() #I don't know why you use np.nansum, but you can pass it like this
c.update(np.nansum(counter2))
c
>>Counter({'c-factor': 0.0,
'dice': 2.0,
'precision': 2.0,
'sensitivity': 2.0,
'specificity': 2.0})
