优化自己的数据集出现问题

作者您好：非常感谢您能将这么好的工作开源出来，在使用该代码测试自己的数据集时出现以下问题，不知道如何解决，请问您是否也遇到此类问题。感谢您的解答！

问题现象:

terminate called after throwing an instance of 'gtsam::IndeterminantLinearSystemException'
  what():  
Indeterminant linear system detected while working near variable
2367 (Symbol: 2367).

Thrown when a linear system is ill-posed.  The most common cause for this
error is having underconstrained variables.  Mathematically, the system is
underdetermined.  See the GTSAM Doxygen documentation at
http://borg.cc.gatech.edu/ on gtsam::IndeterminantLinearSystemException for
more information.

使用数据如下所示:
