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.

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.

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

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。
