Why is the registration registry decorator in mmengine designed to register_module() manually each time?

[vansin]

mmengine 中的注册registry 装饰器为什么要设计成每次手动 register_module() 的形式，为什么不在registry类中添加__call__()函数来解决每次手动注册的问题

Why is the registry decorator in mmengine designed to register_module() manually each time, and why not add call() function to the registry class to solve the problem of manual registration each time

你好，Registry 实现 __call__ 方法并调用 register_module 同样也可以实现注册功能，但直接调用 register_module 会更直观一点。下面是两种用法的对比。

MODEL = Registry('model')

@MODEL()
class ToyModel(nn.Module):
    pass

@MODEL.register_module()
class ToyModel(nn.Module):
    pass
