to sage-devel
so i have install the package
`pip install mathics3` and i get this huge error log
would this be the objective of the project 'Improve integration with Mathics'
or this an isolated error for machine because i can't really i identify the error
i thought it was a mismatch in npmath package but that didn't solve it
and there are a problem when calling the .sage() function to convert the object to a sageobj

It seems to me you would certainly want the interface to work in a manner that is consistent with the other interfaces.
Best,

You are installing an extremely out of data mathics pip package which also forces installation of versions of other packages that are not compatible with SageMath 10.9.
You should run:
%pip install Mathics3
instead.. That works for me.

of course but to be honest still don't understand the problem i am facing
i can't really determine if it's my setup problem or this an existing issue in the source code itself

It is a setup problem. You need to uninstall the pip packages that were installed with the mathics package (and the mathics package itself) and install Mathics3 instead.

that's what i did and resulted and this weird problem

Have you uninstalled mathics (i.e. "pip uninstall mathics"), before
trying Mathics3 ?
There is also a potential problem that "pip install mathics" overwrote
some already installed packages, then "pip unistall" won't restore
them.
There is currently an incompatibility between mathics3 (as installed
by pip from PyPI, maybe the current development version is better),
and Sage packages sympy and mpmath.

i believe The issue is that Sage uses its own mpmath backend (sage.libs.mpmath.ext_main) which replaces the standard mpmath.ctx_mp_python module, but mathics3 was trying to import mpf/mpc from that module.

This should change in the next beta:

thanks i was about to start working on it and reporting it :)

For whatever it is worth, I tested on ubuntu 24.04 with the pre-reelase appimage for Sage 10.9, based on 10.9.beta7 with python 3.14.
After running %pip install mathics3 the commands:
sage: from sage.interfaces.mathics import mathics
sage: mobj = mathics(x^2 - 1); mobj
did not produce any tracebacks. They did produce warnings that there is no module named pkg_resources, which apparently caused some components of mathics to fail to load. Since pkg_resources is not included in Python 3.14 it would seem that mathics doesn't completely support Python 3.14 (yet?).

I can confirm Marc's observation. On the other hand, I can reproduce the bug even with Mathics3 7.0.0 and Sage 10.5.beta3 (from our Docker Hub repository). This constellation is interesting since the last time I successfully tested the Mathics3 interface was with that release (for pull request 37395, which was published in 10.5.beta3).
