NotImplementedError:重载函数Quantlib Python的参数数量或类型错误
NotImplementedError:重载函数Quantlib Python的参数数量或类型错误
提问于 2018-09-05 23:52:02
我是QuantLib新手，刚刚安装了Quantlib和Quantlib-Python。我有MS Visual Studio 2017和2.7.15 64位。
我正在尝试完成Goutham Balaraman的博客(http://gouthamanbalaraman.com/blog/quantlib-basics.html)中的示例。但是，我遇到了一个错误。
代码：
# schedule object can be used to construct a list of dates such as coupon payments
date1 = ql.Date(1, 1, 2015)
date2 = ql.Date(1, 1, 2016)
tenor = ql.Period(ql.Monthly)
calendar = ql.UnitedStates
schedule = ql.Schedule(date1, date2, tenor, calendar, ql.Following, ql.Following, ql.DateGeneration.Forward, False)
schedule
Error:
---------------------------------------------------------------------------
NotImplementedError Traceback (most recent call last)
<ipython-input-5-cae31a33e500> in <module>()
4 tenor = ql.Period(ql.Monthly)
5 calendar = ql.UnitedStates
----> 6 schedule = ql.Schedule(date1, date2, tenor, calendar, ql.Following, ql.Following, ql.DateGeneration.Forward, False)
7 schedule
c:\users\papu\envs\quantlib\lib\site-packages\QuantLib\QuantLib.pyc in __init__(self, *args)
9419
9420 def __init__(self, *args):
-> 9421 this = _QuantLib.new_Schedule(*args)
9422 try:
9423 self.this.append(this)
NotImplementedError: Wrong number or type of arguments for overloaded function 'new_Schedule'.
Possible C/C++ prototypes are:
Schedule::Schedule(std::vector< Date,std::allocator< Date > > const &,Calendar const &,BusinessDayConvention const,boost::optional< BusinessDayConvention >,boost::optional< Period > const,boost::optional< DateGeneration::Rule >,boost::optional< bool >,std::vector< bool,std::allocator< bool > > const &)
Schedule::Schedule(std::vector< Date,std::allocator< Date > > const &,Calendar const &,BusinessDayConvention const,boost::optional< BusinessDayConvention >,boost::optional< Period > const,boost::optional< DateGeneration::Rule >,boost::optional< bool >)
Schedule::Schedule(std::vector< Date,std::allocator< Date > > const &,Calendar const &,BusinessDayConvention const,boost::optional< BusinessDayConvention >,boost::optional< Period > const,boost::optional< DateGeneration::Rule >)
Schedule::Schedule(std::vector< Date,std::allocator< Date > > const &,Calendar const &,BusinessDayConvention const,boost::optional< BusinessDayConvention >,boost::optional< Period > const)
Schedule::Schedule(std::vector< Date,std::allocator< Date > > const &,Calendar const &,BusinessDayConvention const,boost::optional< BusinessDayConvention >)
Schedule::Schedule(std::vector< Date,std::allocator< Date > > const &,Calendar const &,BusinessDayConvention const)
Schedule::Schedule(std::vector< Date,std::allocator< Date > > const &,Calendar const &)
Schedule::Schedule(std::vector< Date,std::allocator< Date > > const &)
Schedule::Schedule(Date const &,Date const &,Period const &,Calendar const &,BusinessDayConvention,BusinessDayConvention,DateGeneration::Rule,bool,Date const &,Date const &)
Schedule::Schedule(Date const &,Date const &,Period const &,Calendar const &,BusinessDayConvention,BusinessDayConvention,DateGeneration::Rule,bool,Date const &)
Schedule::Schedule(Date const &,Date const &,Period const &,Calendar const &,BusinessDayConvention,BusinessDayConvention,DateGeneration::Rule,bool)
Schedule::Schedule()对哪里出了问题有什么帮助吗？

日历应该是ql.UnitedStates()，而不是ql.UnitedStates。现在，您传递的是类本身，而不是它的一个实例。

不是真正的答案，仍然在这里给出，因为答案是正确的格式，而评论是不正确的。
最符合你的参数的重载：
schedule = ql.Schedule(
date1,
date2,
tenor,
calendar,
ql.Following,
ql.Following,
ql.DateGeneration.Forward,
False
)是：
Schedule::Schedule(
Date const &,
Date const &,
Period const &,
Calendar const &,
BusinessDayConvention,
BusinessDayConvention,
DateGeneration::Rule,
bool
)假设ql.DataGeneration.Forward的类型是DataGeneration.Rule，不幸的是我看不出你的代码有什么问题...
