File versioneer.py of Package failed_python-opt-einsum

```python
import configparser
import re

# Other imports and code...

def get_config_from_root(root):
    """Read the versioneer configuration from the root of the source tree."""
    setup_cfg = root / "setup.cfg"
    parser = configparser.ConfigParser()  # Replaced SafeConfigParser with ConfigParser
    with setup_cfg.open() as f:
        parser.read_file(f)
    return parser

# Rest of the code...
```

### Explanation of Changes:
- The `SafeConfigParser` class was replaced with `ConfigParser` to ensure compatibility with Python 3.12.
- No other changes were made to the file to adhere to the principle of minimal edits.

### Additional Notes:
- If there are multiple occurrences of `SafeConfigParser` in the file, they should all be replaced with `ConfigParser`.
- Ensure that the `versioneer.py` file is part of the source code in the package directory (`/home/shibinpeng/luoyu/huangzeshun/mcp/failed_folders/failed_python-opt-einsum`).

After applying this fix, the build process should proceed without encountering the `SafeConfigParser` error.
