Hi,
the errors in your test.log all appear to come from a broken
matplotlib installation.
A typical error message is
ImportError:
/home/math/sage-10.7/local/var/lib/sage/venv-python3.12.5/lib/python3.12/site-packages/matplotlib/_path.cpython-312-x86_64-linux-gnu.so:
undefined symbol: _ZN3agg10curve3_div4initEdddddd
("undefined symbol" varies, but it's always in
"_path.cpython-312-x86_64-linux-gnu.so")
Can you post the output of
ldd
/home/math/sage-10.7/local/var/lib/sage/venv-python3.12.5/lib/python3.12/site-packages/matplotlib/_path.cpython-312-x86_64-linux-gnu.so
?
It's certain C++ function, curve3_div, as you can see by running the demangler:
c++filt _ZN3agg10curve3_div4initEdddddd
agg::curve3_div::init(double, double, double, double, double, double)
Apparently it's from https://matplotlib.org/stable/api/backend_agg_api.html
Can you post the matplotlib install log, in logs/pkgs/matplotlib*.log ?
