Hey Everyone, I recently bought a new computer and I downloaded gem5 using the instructions on the Building Gem5 website (https://www.gem5.org/documentation/general_docs/building), I used the instructions for the newest versions of Ubuntu and gem5 shown on the website (i.e., “Setup on Ubuntu 22.04 (gem5 >= v21.1)”), which allows me to run the newest version of gem5 using this setup. However, I am now trying to run a previous version of gem5 (i.e., gem5 Version 20.1.0.2) for a previous project I was working on, and now I’m getting the following error: > *\*\*\* Error loading site_init file ./site_scons/site_init.py:* > > *\*\*\* cannot import site init file ./site_scons/site_init.py:* > > *ModuleNotFoundError: No module named 'm5':* > > *File "/usr/lib/python3/dist-packages/SCons/Script/Main.py", line 1391:* > > *_exec_main(parser, values)* > > *File "/usr/lib/python3/dist-packages/SCons/Script/Main.py", line 1355:* > > *_main(parser)* > > *File "/usr/lib/python3/dist-packages/SCons/Script/Main.py", line 978:* > > *_load_all_site_scons_dirs(d.get_internal_path())* > > *File "/usr/lib/python3/dist-packages/SCons/Script/Main.py", line 824:* > > *_load_site_scons_dir(d)* > > *File "/usr/lib/python3/dist-packages/SCons/Script/Main.py", line 762:* > > *exec(codeobj, site_m)* > > *File "site_init", line 46:* > > > > *File "/usr/lib/python3/dist-packages/SCons/Script/SConscript.py", line 659:* > > *env = self.factory()* > > *File "/usr/lib/python3/dist-packages/SCons/Script/SConscript.py", line 639:* > > *default_env = SCons.Defaults.DefaultEnvironment()* > > *File "/usr/lib/python3/dist-packages/SCons/Defaults.py", line 86:* > > *_default_env = SCons.Environment.Environment(\*args, \*\*kw)* > > *File "/usr/lib/python3/dist-packages/SCons/Environment.py", line 999:* > > *apply_tools(self, tools, toolpath)* > > *File "/usr/lib/python3/dist-packages/SCons/Environment.py", line 102:* > > *env.Tool(tool)* > > *File "/usr/lib/python3/dist-packages/SCons/Environment.py", line 1844:* > > *tool(self)* > > *File "/usr/lib/python3/dist-packages/SCons/Tool/__init__.py", line 269:* > > *self.generate(env, \*args, \*\*kw)* > > *File "/home/jzell001/Desktop/gem5/gem5_baseline/site_scons/site_tools/default.py", line 89:* > > *SCons.Tool.Tool(tool)(env)* > > *File "/usr/lib/python3/dist-packages/SCons/Tool/__init__.py", line 119:* > > *module = self._tool_module()* > > *File "/usr/lib/python3/dist-packages/SCons/Tool/__init__.py", line 205:* > > *module = spec.loader.load_module(spec.name)* > > *File "<frozen importlib._bootstrap_external>", line 548:* > > > > *File "<frozen importlib._bootstrap_external>", line 1063:* > > > > *File "<frozen importlib._bootstrap_external>", line 888:* > > > > *File "<frozen importlib._bootstrap>", line 290:* > > > > *File "<frozen importlib._bootstrap>", line 719:* > > > > *File "<frozen importlib._bootstrap>", line 688:* > > > > *File "<frozen importlib._bootstrap_external>", line 883:* > > > > *File "<frozen importlib._bootstrap>", line 241:* > > > > *File "/home/jzell001/Desktop/gem5/gem5_baseline/site_scons/site_tools/git.py", line 45:* > > *import gem5_scons.util* > > *File "/home/jzell001/Desktop/gem5/gem5_baseline/site_scons/gem5_scons/__init__.py", line 46:* > > *from gem5_scons.util import get_termcap* > > *File "/home/jzell001/Desktop/gem5/gem5_baseline/site_scons/gem5_scons/util.py", line 45:* > > *import m5.util.terminal* When I tried searching online for an answer to this error, one suggestion was that it had to do with trying to run gem5 with a newer version of Python/Scons. My current versions of Python and Scons are the following: * Python 3.10.6 * Scons 4.0.1 I wanted to see if anyone had any insight into this and if it is because of trying to run an older version of gem5 with too new of versions of Python and/or Scons, do I need to go back to Python 2.7 and an older version of Scons, or will an older version of Python3 work? Thank you for your time! Respectfully, Jason Z.
