python-3.x - AttributeError：模块“m5”没有属性“main”

问题描述

我正在阅读 gem5 教程并尝试在 Ubuntu 20.04 中使用以下脚本运行 gem5：

build/X86/gem5.opt configs/learning_gem5/part1/simple.py

这是教程的链接：
https

://www.gem5.org/documentation/learning_gem5/part1/simple_config/这是我得到的错误：

Traceback (most recent call last):
File "<string>", line 1, in <module>
AttributeError: module 'm5' has no attribute 'main'

我已经检查了 gem5 的邮件存档，它说问题可能出在可以安装在 Python3 中的 M5 包上。
https://www.mail-archive.com/search?l=gem5-users@gem5.org&q=subject:%22%5C%5Bgem5%5C-users%5C%5D+Re%5C%3A+AttributeError%5C %3A+模块+%27m5%27+有+无+属性+%27main%27%22&o=最新&f=1

但是我检查了，M5 没有安装在 Python3 中，而 m5 是。

 >>> import M5
 Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
 ModuleNotFoundError: No module named 'M5'
 >>> import m5
 >>> print(m5.__dict__)

我尝试安装和卸载包 m5。我也尝试从头开始构建 gem5 并再次运行它，但它没有帮助。

任何帮助，将不胜感激。
谢谢你。
