Note: In the above examples, the class hierarchy is very straightforward. The JackRussellTerrier class has a single parent class, Dog. In real-world examples, the class hierarchy can get quite complicated. The super() function does much more than just search the parent class for a method or...
内置数据类型是指在Python中预定义的基本数据类型,包括字符串(str)、列表(list)、元组(tuple)以及字典(dict)等。 对于Python来说,所有的数据类型都继承于object类,object类定义如下: class object | The base class of the class hierarchy. | | When called, it accepts no arguments and returns a new featur...
我们需要明确在python中type和class有区别,建议直接用class和type进行指代。 中层次的理解:builtin.py中object类的定义 class object: """ The base class of the class hierarchy. When called, it accepts no arguments and returns a new featureless instance that has no instance attributes and cannot be ...
In serialization, an object is transformed into a format that can be stored, so as to be able to deserialize it later and recreate the original object from the serialized format.PicklePickling is the process whereby a Python object hierarchy is converted into a byte stream (usually not human ...
numbers supplies a hierarchy (also known as a tower) of ABCs representing various kinds of numbers. numbers supplies the following ABCs: Number The root of the hierarchy: numbers of any kind (need not support any given operation) Complex Extends Number; must support (via the appropriate special...
Scooch config files map parameter configurations directly to python class hierarchies, and so your config file becomes a description of all configurable class's inside your class hierarchy. For example, a class designed to batch samples for training an ML model that uses gradient descent might have...

attempting to marshal recursive objects will crash your Python interpreter. Object sharing happens when there are multiple references to the same object in different places in the object hierarchy being serialized.picklestores such objects only once, and ensures that all other references point to the ...
SSD算法证明了多层分支对于目标检测的有效性,在此之前two-stage的目标检测方法已经优化改进过很多代,但是一直没有加入多尺度的方法。终于在FPN中,two-stage引入了多尺度,并且在SSD多层分支方法的基础上进一步改进,提出了特征金字塔网络。FPN的论文是《Feature Pyramid Networks for Object Detection》。
In addition to the processing order of transitions known from Machine where transitions are considered in the order they were added, HierarchicalMachine considers hierarchy as well. Transitions defined in substates will be evaluated first (e.g. C_1_a is left before C_2_z) and transitions ...
