Unknown assembly set MASTER_NODE1

最近在学abaqus的二次开发，我先通过GUI操作生成rpy文件，然后把它改成.py文件(有删减部分命令行)，然后导入abaqus运行，现在遇到一个问题：
in keyword *EQUATION, file "Job-Testscript.inp", line 75: Unknown assembly set MASTER_NODE1
in keyword *EQUATION, file "Job-Testscript.inp", line 75: Unknown assembly set MASTER_NODE0
in keyword *EQUATION, file "Job-Testscript.inp", line 81: Unknown assembly set MASTER_NODE1
in keyword *EQUATION, file "Job-Testscript.inp", line 81: Unknown assembly set MASTER_NODE0
in keyword *EQUATION, file "Job-Testscript.inp", line 86: Unknown assembly set MASTER_NODE2
in keyword *EQUATION, file "Job-Testscript.inp", line 86: Unknown assembly set MASTER_NODE0
Analysis Input File Processor exited with an error.
就是我明明定义了点集，但是在GUI界面上却没有生成（如图），.py文件，inp文件如附件，求大神指导!
（PS:我通过GUI操作得到的结果是没问题的）
