Question

我当时正在使用django开发的Web应用程序制作路由优化程序，该程序运行正常，但由于某些更改，我猜想我弄错了死记硬背的代码，它向我显示以下错误：

File "/home/chirag/chirag/smartlogistics/lib/python3.7/site-packages/ortools/constraint_solver/pywrapcp.py", line 3191, in __init__
this = _pywrapcp.new_RoutingModel(*args)
NotImplementedError: Wrong number or type of arguments for overloaded 
function 'new_RoutingModel'.
 Possible C/C++ prototypes are:
operations_research::RoutingModel::RoutingModel(operations_research::RoutingIndexManager const &)
operations_research::RoutingModel::RoutingModel(operations_research::RoutingIndexManager const &,operations_research::RoutingModelParameters const &)

我无法弄清楚问题，我是django的新手。任何帮助表示赞赏。谢谢。

以某种方式，您选择了7.0 beta版本，该版本破坏了API。看：
