Stackoverflow when loading PythonPlot

General Usage
, ,
1

This seems to be a python problem, but I’ve often had problems with python that could be solved simply be deleting and re-installing the corresponding packages. So I’m thinking this might be related to how Julia uses python, although this time, even a fresh installation of all of julia didn’t fix it. Loading PyPlot works, but then gives me a stackoverflow later. This one is from calling pythonplot():

Fatal Python error: _Py_CheckRecursiveCall: Unrecoverable stack overflow (used -1601828 kB) while calling a Python object

You’re using python-3.14.0 which is quite new. I’m not sure you’re the first one to try it with plotting, but something changed, and could you at least try older (3.13) for now as a workaround? Python added JIT recently, not sure when it was enabled by default first, maybe in 3.14. Maybe PythonCall news to support it better or something? Or disable it for now, if it’s a problem…

I tried setting /usr/bin/python3.13 in ~/.julia/prefs/PyCall and ENV["PYTHON_JIT"] = 0 prior to calling pythonplot, to no avail. I’m still getting a stack overflow.

edit: that was probably the wrong way to point Julia to python 3.13, particularly considering that I want to use PythonPlot, which uses PythonCall, but I also tried ENV["PYTHON"]="/usr/bin/python3.13", no change.

See Intermittent CI failures: Fatal Python error: _Py_CheckRecursiveCall: Unrecoverable stack overflow · Issue #694 · JuliaPy/PythonCall.jl · GitHub and linked issues.

TLDR Python 3.14 has a new stack overflow detection mechanism that doesn’t interact well with Julia’s execution model. For now you need to roll back to Python 3.13.

I’ll be making a release of PythonCall which restricts to Python 3.13 or older until this is sorted out.
