The last email with my solution wrapped the lines in an odd way, here it is

I have been able to fix the issue with the following commands. They're a little

having issues with getting the correct Python version to be used to build Gem5,

You have found exactly what my issue is!
I'm running out of a python3 virtual environment created / activated with:
"/tools/Python/python3.9.6/bin/python3 -m venv ~/pyenv396"
"source ~/pyenv396/bin/activate"
The issue is that the virtual environment created in this way does not contain

Which Python interpreter to embed is a compile-time decision,
generally controlled by python3-config / python-config. What does
python3-config --ldflags
say? Also, what does 'ldd -r gem5.opt' say about libpython?
You may also want to search for PYTHON_CONFIG in SConstruct to
understand how sco

After rebuilding Gem5, the changes to the "dot_writer.py" are activated. I'll
poke around here and see what I can find.. not sure what's wrong with it yet.
Thanks much,

I have rebuilt after installing pydot, but I don't remember if I did after
changing the "dot_writer.py" file.
I will rebuild again just to be sure.
Thanks much for your help with this.

I would debug it like this:
Near the beginning of dot_writer.py, there is:
try:
import pydot
except:
pydot = False
Replace the "pydot = False" with "import pdb; pdb.set_trace()".
This will drop you into a debug shell where you can investigate why
"import pydot" failed.
