TypeError: cannot unpack non-iterable int objec

TypeError: cannot unpack non-iterable int objec

如何解决此错误 运行 我的代码如下。我正在使用下面的函数并在其上实现 运行 window for 循环,但最终出现以下错误。 for 循环工作并挂在一个点上。

def get_grps(s, thresh=-1, Nmin=3):
    """
    Nmin : int > 0
    Min number of consecutive values below threshold.
    """
    m = np.logical_and.reduce([s.shift(-i).le(thresh) for i in range(Nmin)])
    if Nmin > 1:
        m = pd.Series(m, index=s.index).replace({False: np.NaN}).ffill(limit=Nmin - 1).fillna(False)
    else:
        m = pd.Series(m, index=s.index)

    # Form consecutive groups
    gps = m.ne(m.shift(1)).cumsum().where(m)

    # Return None if no groups, else the aggregations
    if gps.isnull().all():
        return 0
    else:
        agg = s.groupby(gps).agg([list, sum, 'size']).reset_index(drop=True)
        # agg2 = s2.groupby(gps).agg([list, sum, 'size']).reset_index(drop=True)
        return agg, gps

                intensity = np.mean(np.abs(agg['sum'] / agg['size']))
                print(f'intensity {intensity}')

我收到这个错误

 Traceback (most recent call last):

 agg, gps = get_grps(pd.Series(ts), thresh=-1, Nmin=3)
 typeError: cannot unpack non-iterable int object

我该如何解决这个错误?

只需将 return 0 替换为 return 0, 0,或者更好:引发错误而不是 returning 0

当你的if条件为真时,你只有return0。然后稍后,当您执行 agg, gps = get_grps(...) 时,您告诉 python 解包函数的结果。然后,python 期待一个 2 长度的迭代,并尝试解压它,但正如它所说:它 'cannot unpack non-iterable int object'...

所以一个快速的解决方法是 return 元组 (0, 0) 和 return 0, 0,但这很糟糕,因为你 return 预期对象的整数。您的脚本将在下一行 duration = np.nanmean(agg['sum']) 崩溃(因为 agg 为 0)。

处理这种情况的一些更简洁的解决方案是第二次解压:

def get_grps(s, thresh=-1, Nmin=3):
    # ...
    if gps.isnull().all():
        return None
    else:
        # ...
        return agg, gps

for i in range(len(data_spi)-70):
    ts = data_spi[i:i+10, x, y].fillna(1)

    result = get_grps(pd.Series(ts), thresh=-1, Nmin=3)
    if result is None:
        break

    agg, gps = result

    duration = np.nanmean(agg['sum'])
    frequency = len(agg['sum'])

出现了类似的错误,为了解决这个问题,我发布了一个例子。希望能帮到你。

原因:由于 int 内部没有 __itr__ 方法,我们不能像在 listtupledict{}.

x,y,z,n = input() # NOT CONVERTING THE INPUT TO 'INT' HERE  

l = []  

for a in range(0,int(x)): # converting the input to INT  
    for b in range(0,int(y)): # converting the input to INT  
        for c in range(0,int(z)): # converting the input to INT  
            if a+b+c!= n:  
                l.append([a,b,c])  
print(l)

(DJANGO) 在我的例子中,我试图在没有设置搜索参数的情况下获取一个项目:

 schooling = Schooling.objects.get(randint(1, 10)) #Error


 schooling = Schooling.objects.get(id=randint(1, 10)) #OK set id=
