图上蓝色的线将路径固定为1之后,模型的note显示:Iteration limit reached
The results that follow are therefore incorrect.
[color= ]The model is probably unidentified. In order to achieve identifiability, it will probably be necessary to impose 1 additional constraint.
[color= ]提示还需要增加一个限制
[color= ]但我固定其他路径的时候都没有问题,都可以出结果,唯独固定这个不行
