Better uv integration

[mitsuhiko]

This is a meta task to look into actually leveraging uv properly.

• lock with the lower bound of requires-python rather than the current venv version
• make all --prerelease options available
• make all --resolution modes available
• autosync and memorized sync settings #676

[brunorpinho]

Is there a config option to start using rye with uv instead of pip today?

[golgor]

@brunorpinho
See the documentation about the configuration:

# When set to `true` enables experimental support of uv as a replacement
# for pip-tools. Learn more about uv here: https://github.com/astral-sh/uv
use-uv = false

This was also asked during the installation and I have been using it and testing it out today. No real heavy testing, but it works great for me so far.

[mitsuhiko]

Note that for this to work on windows you need the not yet released version as it's disabled for safety reasons on windows still since I did not have time yet to verify basic functionality.

[mjclarke94]

One that might be worth including here for feature completeness is the dependency overrides functionality. A common complaint with poetry is when you have a chain of git repositories dependant on one another (say, pointing at main), an update to one repo breaks everything downstream of it as poetry locks to a specific commit hash.

The overrides functionality in uv could be a fairly lightweight way to bypass this whilst all the repos are in active development.

Does using uv not take into account sources listed in pyproject.toml?

I have the following on my pyproject.toml file:

[[tool.rye.sources]]
name = "pytorch"
type = "index"
url = "https://download.pytorch.org/whl/nightly/cu121"

The lastest stable release of torch is 2.2.0 but I'm trying to download 2.3.0 which is prerelease.

Does not work:

❯ rye add torch
Added torch>=2.2.0 as regular dependency

Does not work:

❯ rye add --pre torch
Added torch>=2.2.0 as regular dependency

Seems like rye is constructing a similar command argument as the following. Based on the add.rs file

❯ VIRTUAL_ENV=.venv uv pip compile --no-deps --no-header --python-version 3.11.7 --prerelease=allow -
torch
Resolved 1 package in 1.54s
torch==2.2.0

But if try to install directly with uv, it does work:

[mitsuhiko]

@sbarrios93 yes, looks like a bug. I will fix that.

[sbarrios93]

@mitsuhiko, I'm assuming that a fix would involve setting the default source in config.toml for rye (usually PyPi) as --index-url, with any additional index sources as --extra-index-url. However, based on astral-sh/uv#1451 (comment), I'm guessing that such a fix on rye's side wouldn't fix the resolution issue.

I've added some insights specific to PyTorch in astral-sh/uv#1723, which I closed in favor of astral-sh/uv#1451.

I don't want to hijack this thread – let me know if it's better to open a separate issue for this discussion.

rye add with --features currently does not work when uv is enabled.

[mitsuhiko]

This at the very least is triggering a weird code path in uv. I filed it there for now: astral-sh/uv#1801

Could be trivially worked around on the rye side though if needed.

[osuchw]

Thank you for looking into it. There is no more panic with rye 0.26.0 but --features is being ignored.
There is #745 now with more details.

[utkarshgupta137]

Not sure if this is the right place, but I can't figure out an easy way to get rye (with uv enabled) to update my rust deps.
Currently (rye 0.29.0, no uv), when I run rye sync --no-lock, it re-installs all workspace members, including re-building all the rust dependencies:

$ rye sync --no-lock -v

With uv enabled, I get the following:

Where proj-entrypoint & proj-toolbox are rust crates & proj depends on both of them.
It would be nice if I could pass a flag to force rye to re-build my rust dependencies or better yet, have it automatically figure it out.

[geoqiao]

Will rye add -r requirements.txt be supported, just like uv pip install -r requirements.txt or something like that?

It's needed when clone some projects which not init by rye

[bluss]

@geoqiao Rye init already supports importing requirements files

Edit: Indeed, as you say, it seems like it's not documented.

[bluss]

I'll suggest here that uv's --offline flag could be made available on rye lock and rye sync.

[geoqiao]

@geoqiao Rye init already supports importing requirements files

Sorry, I didn't find in doc. Could you teach me how to do that? Thanks!

[geoqiao]

@geoqiao Rye init already supports importing requirements files

Thanks for your reply, I found the -r option in the command line section of the document

[MilesCranmer]

Friendly ping. Is there any way to pass --prerelease=allow to rye? I got hit with this today and literally can't install a package with rye because of it:

Reusing already existing virtualenv
Generating production lockfile: /Users/mcranmer/PermaDocuments/spock/requirements.lock
  × No solution found when resolving dependencies:
  ╰─▶ Because there is no version of exoplanet-core==0.3.0rc2 and celmech==1.5.0 depends on exoplanet-core==0.3.0rc2, we can conclude that celmech==1.5.0 cannot be used.
      And because you require celmech==1.5.0, we can conclude that the requirements are unsatisfiable.

      hint: exoplanet-core was requested with a pre-release marker (e.g., exoplanet-core==0.3.0rc2), but pre-releases weren't enabled (try: `--prerelease=allow`)
error: could not write production lockfile for project

Caused by:
    Failed to run uv compile /var/folders/1h/xyppkvx52cl6w3_h8bw_gdqh0000gr/T/.tmpgCC8Dh/requirements.txt. uv exited with status: exit status: 1

but alas, I cannot seem to pass this option through to uv.

[charliermarsh]

@MilesCranmer - I can look into adding it. Note that you can work around this by telling uv to allow pre-releases for exoplanet-core specifically, by adding a requirement like:

exoplanet-core >= 0.3.0rc2

As long as you include some pre-release segment in the specifier, we'll enable pre-releases for that dependency.

[MilesCranmer]

Awesome. Thanks!

[bluss]

@MilesCranmer have you had any success using rye sync --pre ?

[MilesCranmer]

Yep, that did it, thanks! (Unfortunately it was a dependency of a dependency, so putting it as an explicit dependency wasn't optimal)

Maybe the error message could point out the --pre flag? Right now the error is from uv and only mentions the --prerelease one.
