python - 集成导致TypeError : 'numpy.float64' object cannot be interpreted as an integer

亲爱的 friend ，我在运行Python后发送了错误代码，并编写了大量代码:
抱歉，这个问题是业余的。

dacdm = 1/(z+1) * cdm
TypeError: 'numpy.float64' object cannot be interpreted as an integer

这是错误的最后2句话。 Python错误地提到了我的代码的以下部分，因此我确定错误来自此处:

def H_LCDM(z, H0, DM0):
        lcdm = 1/(H0 * sqrt(DM0 * (1 + z)**3 + (1 - DM0)))
        return lcdm

def DA_LCDM(z, DM0, H0):
         cdm = quad(H_LCDM, 0, z, args = (H0, DM0))
         dacdm = 1/(z+1) * cdm
         return dacdm


def fg(gg, DM0, H0, A, alpha, b, Omb):
        h = H0/100
        f_th = (0.824 /(1 + 0.19 * (h)**(1/2)))* (Omb/DM0) * (DA_LCDM(zgas[gg], H0, DM0)/DA(zgas[gg], DM0, H0, A, alpha, b))
        fgasth = ((fgas[gg] - f_th)/siggas[gg])**2
        return fgasth

def fgasmass(DM0, H0, A, alpha, b, Omb):
    h = H0/100
    num=0
    for gsgs in range(len(zgas)):
        num = num + fg(gsgs, DM0, H0, A, alpha, b, Omb)
        return num + ((Omb * h**2 - 0.0214)/0.002)**2 + ((h - 0.72)/0.08)**2

我无法找到问题的根源。

有关更多信息，我将整个错误放在这里:

非常感谢。

最佳答案

cdm是一个序列，而不是数字。 quad可能是 scipy.integrate.quad ，它返回一个最多包含5个元素的元组，而不仅仅是一个整数。带有序列的*期望一个整数，该整数表示重复该序列的次数；例如，我们有

>>> 3 * (1, 2, 3)
(1, 2, 3, 1, 2, 3, 1, 2, 3)

如果quad是scipy.integrate.quad，则积分是元组的第一个元素，因此，如果需要积分，请从结果中索引它:

#                                         vvv
cdm = quad(H_LCDM, 0, z, args = (H0, DM0))[0]

另外，将来，请阅读文档以获取使用的功能。
