Are we likely to get an &quot;uv upgrade&quot; command that makes sense sometime?It&#x27;s still very obtuse how to get uv to just try and make all my dependencies the highest version possible.

It makes `uv run &lt;project-name&gt;` work by default, I expect most projects to need an entry point.

The thing where &quot;uv init&quot; now adds this to pyproject.toml is a bit surprising:<pre><code> [project.scripts]
 demo-latest = &quot;demo_latest:main&quot;
</code></pre>
What&#x27;s the rationale for that? My expectation is that few projects would need it.

Yes! We&#x27;ve been working on this for quite some time as it&#x27;s one of the worst experiences in Python packaging today.There are two PEPs that we&#x27;re involved with that will provide the components for the ecosystem to properly declare metadata in this domain [1] [2].We&#x27;re also working on some features in uv, such as the torch backend option [3], to improve the situation in the interim.We&#x27;ll be announcing more in this area in the near future![1] <a href="https:&#x2F;&#x2F;peps.python.org&#x2F;pep-0817&#x2F;" rel="nofollow">https:&#x2F;&#x2F;peps.python.org&#x2F;pep-0817&#x2F;</a>

Maybe a naive question, but any goal &#x2F; progress towards an ”it just works” cuda installation? Currently, the only times i feel like i‘m stumbling over an install with uv is when pytorch &#x2F; cuda is involved.

Pixi is very focused on the Conda ecosystem and implements a sort of bridge across the Conda and PyPI ecosystems. I am very interested in solving the problems that motivated creation of the Conda ecosystem, but I want to do so by driving forward the PyPI ecosystem so those use-cases can be addressed in _many_ tools instead of just one. This is the main reason you don&#x27;t see us pursuing Conda package support in uv directly (in the style of Pixi).There have been several threads about us collaborating or converging, but there are no concrete plans to do so at this time. We share some Rust crates, e.g., Pixi uses our internals to solve the PyPI-side of their dependencies, and we occasionally fix or change things for each other.

How do you think of uv vs pixi?Follow up: has anyone suggested the projects collaborate or eventually converge?

We have the interface because we care a lot about meeting people where they are.We keep the interface because we care a lot about long-term support and compatibility. I cannot imagine removing it.We generally want to add features to the top-level interface such that people don&#x27;t need or want to use the pip-interface because the top-level interface does everything you need, but better.

It’s widely used, and there are still a lot of workflows that we hear about from users where they want&#x2F;need to manually twiddle environments rather than having the “declarative” layer do it for them.

uv pip is a brilliant adoption gateway, you get all of the speed gains for a 3 char change

Has anything changed in your day by day work since OpenAI acquisition?

Unfortunately dynamic metadata is not efficient for package resolution, so we don&#x27;t want to encourage it. Instead, we want to design a better workflow for using source control for versioning, but haven&#x27;t had the time to do so.

Bit surprised, and disappointed to not see dynamic field support for the uv build backend in this update. Need it for dynamically getting the version from Git. Is there anything blocking it, or is it just not important enough?

Or an obscure CalVer that no one realizes - &#x2F;pip-maintainer

What&#x27;s blocking a 1.0 release at this point?

WDYM by madness? I know what the flag is (and what it does), but people have strong opinions in opposite directions about what Python packaging should do around system environments.

I think we&#x27;re doing what we should making isolated environments easy to use. I don&#x27;t think we should take options away from people that need them.

Can you stop the --break-system-packages madness?

This is our first breaking release since March. We’re happy to answer any questions folks have about it.

thoughts on worm safety w.r.t. `exclude-newer`, and the right way to handle unpinned git repo deps?
