What the bug is, and how to reproduce, better with screenshots(描述bug以及复现过程，最好有截图)

• 拉取最新代码后（swift 3.5.0.dev0），使用官方推荐的安装方法pip install -e .[all]，会因为包的版本依赖混乱导致报如下错：

..........
 Preparing metadata (setup.py) ... done
Collecting attrdict (from ms_swift==3.5.0.dev0)
  Using cached https://mirrors.cloud.tencent.com/pypi/packages/35/bb/bac3e42ae04bc082c28cd8186bfb5b50fb240a4f7419f876c683125ccc8b/attrdict-2.0.0.tar.gz (9.0 kB)

error: resolution-too-deep

× Dependency resolution exceeded maximum depth
╰─> Pip cannot resolve the current dependencies as the dependency graph is too complex for pip to solve efficiently.

hint: Try adding lower bounds to constrain your dependencies, for example: 'package>=2.0.0' instead of just 'package'.

• 若使用旧版本（v3.0.1）则正常安装。
  初步分析是推荐的包版本混乱导致，请问是否可以提供一个可正常执行的包版本？

pip install ms-swift -U或者 pip install -e .试试

谢谢@Jintao-Huang
pip install -e .可正常执行，请问pip install -e .[all]为何不能使用呢？
pip install -e .也是全能力吗

[Jintao-Huang]

除了eval和xtuner(序列并行)没有安装吧，其他都可以的

好的，感谢 @Jintao-Huang
