并向其传入一个回调函数（具体稍后解释）。call_soon会将这个回调函数注册到事件循环上面去，以便事件循环可以在下次循环的时候取出并执行。这里Task传入call_soon的回调函数其实就是自己的__step方法 。虽然在代码注释中并没有提及这个方法的具体作用，但是顾名思义这个方法是用来触发这个task的执行的。这个方法很重要，我们马上
stop() - called once when the codelet is stoppedUnlike the C++ codelets, all the python codelets are registered via a same interface namely: nvidia::gxf::PyCodeletV0.To implement a codelet in python, users have to implement the class CodeletAdapter. As explained above, the users implement ...

In CPython, the global interpreter lock, or GIL, is a mutex that prevents multiple native threads from executing Python bytecodes at once. This lock is necessary mainly because CPython’s memory management is not thread-safe. (However, since the GIL exists, other features have grown to depe...

The call to .waste_time() isn’t timed.Later, you’ll see an example defining a proper class decorator, namely @singleton, which ensures that there’s only one instance of a class.Remove ads Nesting DecoratorsYou can apply several decorators to a function at once by stacking them on top...
YOLO是You Only Look Once的缩写,意思是神经网络只需要看一次图片，就能输出结果。YOLO 一共发布了五个版本，其中 YOLOv1 奠定了整个系列的基础，后面的系列就是在第一版基础上的改进，为的是提升性能。YOLOv5有4个版本性能如图所示：4.1 网络架构图 YOLOv5是一种单阶段目标检测算法，该算法在YOLOv4的基础上...
