**关键技术点**：
- **约定式提交**（Conventional Commits）格式：

<类型>[可选作用域]: <描述>

[可选正文]

[可选脚注]

- 类型包括：feat(新功能)、fix(修复)、docs(文档)、style(格式)、refactor(重构)、perf(性能)、test(测试)、build(构建)

### 2.3 RMBG项目版本控制现状分析

通过对项目文件的系统分析，发现当前版本管理存在以下问题：

1. **版本号散落**：
 - config.json中存在"_name_or_path": "briaai/RMBG-1.4"
 - README.md提到"New RMBG version available! Check out RMBG-2.0"
 - 但未在代码中定义`__version__`变量（搜索*.py文件未发现版本定义）

2. **缺乏变更记录**：
 - 项目根目录未找到CHANGELOG.md文件
 - 提交历史未采用约定式提交规范
 - 无法追溯1.4.0版本的具体变更内容

3. **版本验证缺失**：
 - requirements.txt仅指定transformers>=4.39.1，未锁定依赖版本
 - 缺少版本兼容性测试用例

## 三、落地实践：从零构建RMBG版本控制系统

### 3.1 版本号管理实现

**第一步：在MyConfig.py中添加版本定义**

```python
from transformers import PretrainedConfig
from typing import List

class RMBGConfig(PretrainedConfig):
  model_type = "SegformerForSemanticSegmentation"
  VERSION = "1.4.0"  # 主版本.次版本.修订号
  
  def __init__(
      self,
      in_ch=3,
      out_ch=1,
      **kwargs):
    self.in_ch = in_ch
    self.out_ch = out_ch
    super().__init__(** kwargs)
    
  @property
  def version_tuple(self):
      return tuple(map(int, self.VERSION.split('.')))

第二步：创建版本管理工具version.py

import re
from pathlib import Path

VERSION_PATTERN = re.compile(r'VERSION\s*=\s*"(\d+\.\d+\.\d+)"')
FILES_TO_UPDATE = [
    "MyConfig.py",
    "config.json",
    "README.md"
]

def get_current_version():
    with open("MyConfig.py", "r") as f:
        match = VERSION_PATTERN.search(f.read())
        return match.group(1) if match else "0.0.0"

def update_version_files(new_version):
    for path in FILES_TO_UPDATE:
        content = Path(path).read_text()
        if path == "config.json":
            updated = re.sub(
                r'"_name_or_path":\s*"briaai/RMBG-\d+\.\d+"',
                f'"_name_or_path": "briaai/RMBG-{new_version}"',
                content
            )
        elif path == "MyConfig.py":
            updated = VERSION_PATTERN.sub(f'VERSION = "{new_version}"', content)
        elif path == "README.md":
            updated = re.sub(
                r'RMBG-\d+\.\d+', 
                f'RMBG-{new_version}', 
                content
            )
        Path(path).write_text(updated)

3.2 CHANGELOG自动化配置

安装python-semantic-release

pip install python-semantic-release
semantic-release init

配置setup.cfg

[semantic_release]
version_toml = pyproject.toml
upload_to_pypi = false
upload_to_release = true
branch = main
build_command = python -m build
commit_author = "Version Bot <bot@example.com>"

创建CHANGELOG.md模板
