我的程序如下：
1 ]+ c, A! [9 c; abreed [dogs dog]. f+ g4 S& E; s- O% V7 R

这个是netlogo自带模型库里的模型中的程序，我新建文件再将其输入却提示错误：
8 m% J! [- ~8 h0 `error while observer running SET-DEFAULT-SHAPE in procedure SETUP5 D, i( Q/ i" {
"dog" is not a currently defined turtle shape

8 i! K! t9 f3 B0 Z8 k* q5 M我用的版本是4.0.4 请大虾们指教下。thanks！ |
