从pmdarima导入auto_arima时:错误:无法从'scipy.misc'导入名称'factorial' [英] While importing auto_arima from pmdarima: ERROR : cannot import name 'factorial' from 'scipy.misc'

问题描述

我有python 3.7.1和scipy版本:1.3.0.调用auto_arima时出现错误:无法从'scipy.misc'导入名称'factorial'"

I have python 3.7.1 and scipy version : 1.3.0. I'm getting error while calling auto_arima saying : "cannot import name 'factorial' from 'scipy.misc'"

此基本导入会导致问题:-
从pmdarima.arima导入auto_arima"
我尝试重新安装scipy，但没有成功

Just this basic import causes the issue:-
"from pmdarima.arima import auto_arima"
I've tried reinstalling scipy, didn't work

推荐答案

功能factorial从scipy.misc移到了scipy.special. scipy.misc中的版本已被弃用一段时间，并在scipy 1.3.0中删除. pmdarima中的某物或其依赖项之一仍使用名称scipy.misc.factorial.

The function factorial was moved from scipy.misc to scipy.special. The version in scipy.misc has been deprecated for a while, and it was removed in scipy 1.3.0. Something in pmdarima or one of its dependencies is still using the name scipy.misc.factorial.

罪魁祸首似乎是统计模型0.9.0. pmdarima取决于statsmodels，并且statsmodels 0.9.0中有导入scipy.misc.factorial的代码. statsmodels的开发版本已对此进行了修复，但最新版本为0.9.0.如果将statsmodels升级到0.10或更高版本，则应解决此问题.

The culprit appears to be statsmodels 0.9.0. pmdarima depends on statsmodels, and there is code in statsmodels 0.9.0 that imports scipy.misc.factorial. The development version of statsmodels has a fix for that, but 0.9.0 is the latest release. The problem should be fixed if you upgrade statsmodels to version 0.10 or later.

statsmodels开发人员已意识到该问题；见
