一、机器学习和深度学习简介 深度学习的主题最近非常受欢迎,在这个过程中,出现了几个术语,使区分它们变得相当复杂。人们可能会发现,由于主题之间大量的重叠,将每个领域整齐地分开是一项艰巨的任务。 本章通过讨论深度学习的历史背景以及该领域如何演变成今天的形式来介绍深度学习的主题。稍后,我们将通过简要介绍基础主题来...
obj = type->tp_new(type, args, kwds); # 这里先执行tp_new分配内存、创建对象返回obj obj = _Py_CheckFunctionResult((PyObject*)type, obj, NULL); ... type = Py_TYPE(obj); # 这里获取obj的class类型,并判定有tp_init则执行该初始化函数 if (type->tp_init != NULL) { int res = type-...

The class’s initializer, .__init__(), takes radius as an argument and makes sure that the input value is a positive number. This check prevents circles with a negative radius. The .area() method computes the circle’s area. However, before doing that, the method uses an assert stateme...
# Define a function to find the first missing positive integer in a list def first_missing_number(nums): # Check if the list is empty, return 1 if it is if len(nums) == 0: return 1 # Sort the list in ascending order nums.sort() # Initialize the smallest positive integer as 0 ...
watchpoints will use the copy function you provide to copy the object for reference, and use your compare function to check if that object is changed. If copy function or compare function is not provided, it falls to default as mentioned above. ...
First, it uses the built-in isinstance() function to check if the value is an integer number. Then it checks if the input value is greater than 0. If either of these conditions fails, then the statement raises an AssertionError with the provided message as an argument....
Once we have built a modelforpredicting the classification of data, we need to validate the model. This means we have to test the modelwithsome previously unseen dataandcheck whether it correctly classifies the new data. For this, we can use `classification_report`, which takes a newsetof ...
