# lazy_config

剥离 detectron2 的 LazyConfig 功能，用于通用任务的项目模板。

## How to create your own package based on this package.

```bash
python init.py
```

and follow the prompts.

After the project is created, you can delete the `init.py` file and start working on your project.

## Usage

See the example in `projects/lazy_config_demo/main.py` and run it with the following command:

```
PYTHONPATH=. python projects/lazy_config_demo/main.py projects/lazy_config_demo/config.py MODEL.in_features=10
```

## Principles

- `LazyCall` (or `L`): 这是让你能够以惰性方式定义对象构建的语法糖。

- `instantiate()` function: 这是将惰性配置（带有 _target_ 的 omegaconf 对象）转换为实际 Python 对象的关键函数。它会处理递归实例化和参数传递。

- `parse_args_and_configs()` function: 它允许你读取命令行参数和配置文件，并将它们合并成一个 omegaconf 对象。
