尝试使用Gem5toMcpat生成configFileName.xml时，如何解决“ KeyError：'cpu'”错误？

Question

您好，我正在尝试通过在ubuntu 20上安装的Gem5toMcpat解析器中使用以下命令来生成configFileName.xml

 python Program.py stats.txt  config.json  ARM_A9_2GHz.xml

但是它显示了这个错误

Traceback (most recent call last):
  File "Program.py", line 964, in <module>
    main()
  File "Program.py", line 38, in main
    countCores(sys.argv[2])
  File "Program.py", line 70, in countCores
    noCores = len(configfile["system"]["cpu"])
KeyError: 'cpu'
