我的程序如下：
$ C+ X% \7 [, ?. bbreed [dogs dog]9 }6 l$ [, g1 I! k1 S5 y
breed [cats cat]
9 t$ I3 \( o$ h( o. j7 obreed [cows cow]* ^. |. x7 s% S L1 @) d/ r* C

4 L; r+ O8 @0 B d1 x1 Z ask patch 0 1 [ sprout-dogs 1 ]( b6 S) P$ }, j S& X9 ]' V

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：7 P6 |$ ^" y4 y, ~
error while observer running SET-DEFAULT-SHAPE in procedure SETUP
