Python错误“ AttributeError：模块'scipy.misc'没有属性'logsumexp'”

Question

I'm trying to use the lifetimes header to create the Recency, Frequency and T from a given data but it keeps showing the following error AttributeError: module 'scipy.misc' has no attribute 'logsumexp'

from lifetimes.plotting import *
from lifetimes.utils import *
from lifetimes.estimation import *
data = summary_data_from_transaction_data(df, 'CustomerID','InvoiceDate', monetary_value_col='Sales', observation_period_end='2011-12-9')
print(data.head())

The following output is received:

Traceback (most recent call last):

logsumexp = primitive(scipy.misc.logsumexp)
AttributeError: module 'scipy.misc' has no attribute 'logsumexp'

The version of SciPy is 1.3.0 The code should generate a table with Recency, Frequency and T of each Customer

Answer 1

降级为scipy == 1.1.0解决了该问题

Answer 2

from scipy.misc import logsumexp更改为from scipy.special import logsumexp
