我正在尝试运行生命线包，

import numpy as np
from scipy import stats
import pandas as pd
from scipy.special import logsumexp
from lifelines import KaplanMeierFitter, CoxPHFitter
from lifelines.statistics import logrank_test

结果证明

      8 
      9 def make_grad_logsumexp(ans, x, axis=None, b=1.0, keepdims=False):

AttributeError: module 'scipy.misc' has no attribute 'logsumexp'

我知道 logsumexp 已从 scipy.misc 中删除并放置在 scipy.special 中。以前有人建议将 SciPy 降级到 1.1.0 版本。但是，如果我将代码从

logsumexp = primitive(scipy.misc.logsumexp)

至

logsumexp = primitive(scipy.special.logsumexp)

如果可能的话，我可以知道如何修改代码吗？这段代码在 Scipy.misc 中还是在生命线中？
