Question

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

      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logumexp已从scipy.misc中删除，并放在scipy.special中。以前，有人建议将SciPy降级到1.1.0版本。但是，如果我从

更改代码会更容易

logsumexp = primitive(scipy.misc.logsumexp)

到

logsumexp = primitive(scipy.special.logsumexp)

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

无法加载生命线（结果显示：属性错误：模块'scipy.misc'没有属性'logsumexp'）
