marimo/_runtime/packages/module_name_to_pypi_name.py: Add mapping for sage

[mkoeppe]

📝 Summary

Map the namespace sage to the package https://pypi.org/project/passagemath-standard/

🔍 Description of Changes

The default mapping by marimo for the namespace sage leads to the uninstallable dummy package https://pypi.org/project/sage/

Following the instructions at https://docs.marimo.io/guides/editor_features/package_management/, this PR provides a mapping of the namespace sage to the pip-installable package passagemath-standard, which provides this namespace via its numerous dependencies, each pip-installable from binary wheels on PyPI. @akshayka

For a more fine-grained mapping to the modularized pip-installable packages of passagemath, progress on the following issue will be needed.

• module_name_to_pypi_name to support matching modules like "azure.identity" or "azure.storage.blob" #2841

Thanks for the PR. Isn't the standard distribution sagemath-standard?

[mkoeppe]

sagemath-standard was discontinued by the SageMath project after August 2025, see https://pypi.org/project/sagemath-standard/#history

[mkoeppe]

The SageMath project now provides only https://pypi.org/project/sagemath, but that does not provide binary wheels, as can be seen in https://pypi.org/project/sagemath/#files, so it is not suitable in the molab cloud.

[dmadisetti]

Ah, ok. We can also pre-package the bins for molab, but I think the official sage distribution is what most users would expect

[mkoeppe]

The official Sage distribution is not compatible (any more...) with installation via pip / uv.

Edit: see passagemath/passagemath#1508 (comment)

[dmadisetti]

I'm going to close this out in favour of #7153 - but thank you for your enthusiasm. We'll make sure that sage works seamlessly on molab

[mkoeppe]

I strongly recommend actually testing the "sage" build via sagemath suggested in #7153 and not rely on what is claimed there before making this decision. The person who opened it is not a reliable narrator.

As you can see in the instructions that the person there is referring to, numerous dependencies (system packages) need to be installed, either using conda, or from a suitable Linux distribution before "pip install" / "uv install" can succeed. It will also need these system packages at runtime, not just a prebuilt wheel. It is unlikely that the marimo project will want to take on the maintenance of this.

Claims that the SageMath project is "working on providing binary wheels" are false. On the contrary, the existing infrastructure for making binary wheels, such as https://pypi.org/project/sagemath-objects/10.5/#files (from December 2024), was discontinued in early 2025. References on this:
