python-AttributeError:“模块”对象没有属性“ DefaultRoutingSearchParameters”
作者:互联网
我已经完全按照this链接中所述安装了ortools.
之后,我从文档中复制了车辆路线问题并尝试执行.我在系统中使用python 2.7.12.
我最终遇到以下错误:
>>python or_test.py
Traceback (most recent call last):
File "or_test.py", line 120, in <module>
main()
File "or_test.py", line 52, in main
search_parameters = pywrapcp.DefaultRoutingSearchParameters()
AttributeError: 'module' object has no attribute
'DefaultRoutingSearchParameters'
问题链接示例:

解决方法:
基于example from the repo,您可以改为使用以下默认参数:
search_parameters = pywrapcp.RoutingModel.DefaultSearchParameters()
