uv install error #472

NBdadasama · 2025-05-09T01:07:50Z

I did not get any pyav related errors during my previous installation, but recently I got this error in a new environment.

jerry007005 · 2025-05-09T02:46:26Z

I just got the same error here. Looking for help

I failed with uv install today on cluster, I was also able to install the env on my local desktop few days ago with exact the python 3.11.12

The desktop os version:

Distributor ID: Ubuntu
Description: Ubuntu 22.04.5 LTS
Release: 22.04

The cluster os version:

LSB Version: :core-4.1-amd64:core-4.1-noarch
Distributor ID: Rocky
Description: Rocky Linux release 9.4 (Blue Onyx)
Release: 9.4
Codename: BlueOnyx

haohuanw · 2025-05-09T07:26:47Z

we haven't tested anything with Rockylinux on our end. is it possible to use ubuntu? Alternatively, you could run with an ubuntu container on your cluster.

NBdadasama · 2025-05-09T08:00:19Z

If I use docker to build, this error will not appear. A week ago, I used the official command to configure the environment and there was no error. But recently, this error will appear. I still get this error when I install the pyav related packages. I may not be good at using uv. It may have an advantage in python package management, but I am better at using conda.

haohuanw · 2025-05-09T09:26:13Z

i have also tried with 3.11.12 on ubuntu and it works fine:

could you double check and make sure there are no accidental modifications to either pyproject.toml or uv.lock file?

jinPrelude · 2025-05-09T09:33:28Z

The root cause isn’t OpenPI itself—it’s the outdated lerobot commit the repo is pinned to. That old commit still depends on the package name pyav, which is wrong; the library is now published as av. Seems like this was fixed upstream in lerobot at commit ed83cbd4f2091a3e97cdd0c48cc657020c037240.

If you manually bump the lerobot hash in uv.lock, the installation goes through, but you’ll then hit other incompatibilities because OpenPI was written against the older lerobot API. The long-term fix is for OpenPI to update its lerobot reference to at least ed83cbd and adjust any breaking changes accordingly.

I’m not sure whether we can simply patch the install script to pull av in place of pyav while still using the original lerobot commit.

NBdadasama · 2025-05-09T09:35:06Z

根本原因并非 OpenPI 本身，而是该仓库所绑定的过时的 lerobot 提交。该旧提交仍然依赖于包名 pyav，而这个包名是错误的；该库现在以 av 的形式发布。这个问题似乎已在 lerobot 上游的提交中得到修复ed83cbd4f2091a3e97cdd0c48cc657020c037240。

如果您在 uv.lock 中手动修改 lerobot 哈希值，安装过程会顺利进行，但随后会遇到其他不兼容问题，因为 OpenPI 是基于较旧的 lerobot API 编写的。长期解决方案是让 OpenPI 将其 lerobot 引用更新到至少 ed83cbd，并相应地调整任何重大更改。

我不确定我们是否可以简单地修补安装脚本以将 av 替换为 pyav，同时仍然使用原始的 lerobot 提交。

i think that is the reason.

haohuanw · 2025-05-09T13:30:33Z

The root cause isn’t OpenPI itself—it’s the outdated lerobot commit the repo is pinned to.

it's possible but unlikely to be the case in my opinion since it won't explain why another fresh installation inside the container still works (there are no uv cache exists). uv.lock contains a package as pyav with links that are still valid: https://github.com/Physical-Intelligence/openpi/blob/main/uv.lock#L3274-L3298

since i am not able to repro it in any environment that is available to me, you can follow these steps as a workaround to unblock yourself if it could fix the issue:

create a fork on lerobot
on the forked repo, checkout https://github.com/huggingface/lerobot/commit/6674e368249472c91382eb54bb8501c94c7f0c56 update pyav deps and cherry-pick https://github.com/huggingface/lerobot/commit/ed83cbd4f2091a3e97cdd0c48cc657020c037240. Push the change.
in your openpi, update https://github.com/Physical-Intelligence/openpi/blob/main/pyproject.toml#L61 with lerobot = { git = "https://github.com/<your username>/lerobot", rev = "<newly pushed commit>" }
then uv sync to sync with an updated lerobot repo.

forresti · 2025-05-09T21:23:52Z

I am having the same problem. I'm using ubuntu 24.04.

Before

In uv.lock, we have:

[[package]]
name = "lerobot"
version = "0.1.0"
source = { git = "https://github.com/huggingface/lerobot?rev=6674e368249472c91382eb54bb8501c94c7f0c56#6674e368249472c91382eb54bb8501c94c7f0c56" }
dependencies = [
  ...
]

In the above, we have rev=6674e368249472c91382eb54bb8501c94c7f0c56. That's a commit in lerobot from Feb 1, 2025.

Also, in pyproject.toml, we have

lerobot = { git = "https://github.com/huggingface/lerobot", rev = "6674e368249472c91382eb54bb8501c94c7f0c56" }

After

I updated uv.lock to the latest lerobot commit: a445d9c9da6bea99a8972daa4fe1fdd053d711d2. Specifically, I do this:

[[package]]
name = "lerobot"
version = "0.1.0"
source = { git = "https://github.com/huggingface/lerobot?rev=a445d9c9da6bea99a8972daa4fe1fdd053d711d2#a445d9c9da6bea99a8972daa4fe1fdd053d711d2" }
dependencies = [
  ...
]

I updated pyproject.toml:

lerobot = { git = "https://github.com/huggingface/lerobot", rev = "a445d9c9da6bea99a8972daa4fe1fdd053d711d2" }

Then, I rerun GIT_LFS_SKIP_SMUDGE=1 uv sync, and then GIT_LFS_SKIP_SMUDGE=1 uv pip install -e ..

It installs this time without an error!

xiaoen0 · 2025-05-23T03:38:12Z

I am having a similar problem.

I replaced all occurrences of pyav with av in both pyproject.toml and uv.lock, and it worked.

markattarcolgate64 · 2025-05-23T05:56:23Z

Also having this problem and I'm having it in Colab don't know if that is related, but it seems like that other people are also having the issue in other environments
