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.

Use the following command to create a new package based on this package:

python init.py your-package-name

It will replace the current package name (lazy_config) with your own package name in the code base.

However, you need to modify the author name and email in pyproject.toml.

Then you should use pip install -e .[dev] to install the package in editable mode.

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。
