python函数中万能参数*args、**kargs的应用

ESP32 MicroPython开发之旅 基础篇⑤ ——*args,**kwargs可变参数 讲解Python里面的一些常见参数包括*args,**kwargs,方便容易理解python第三方库。 阅读详情

“”"
实参角度:
1.位置参数,按照顺序一一对应 (a,b,c)对应(1,2,3)
2.关键字参数,一一对应,不用顺序 (a,b,c)对应(a=1,b=2,c=3)
3.混合参数:位置参数一定要在关键字参数之前 (a,b,c)对应(1,c=3,b=2)
形参角度:
1.与实参角度的位置参数是一种
2.默认参数:(a,b,mode = “r”)
普遍的经常使用的
3.万能参数
4.*的魔性用法
5.极限关键字参数(了解)
6.形参的最终顺序
return:可返回多个值,以元组形式返回
“”"

函数要留有修改的接口,源码一般不改变,需要一种形参可以接受所有的实参,所以出现了*args、**kwargs

*args
在这里插入图片描述**kwargs
在这里插入图片描述形参的顺序:位置参数,*args,默认参数,仅限关键字参数,**kargs在这里插入图片描述**在函数的调用时,代表打散

集成电路设计笔记(七)UVLO设计

1. 什么是UVLO 欠压锁定(Undervoltage-Lockout)简称UVLO,是电子设备中在电源电压低于正常工程准位时,切断电源的电路。在嵌入式系统中常会用UVLO监控电池电压,若电压低于一定值,会直接切断电源,保护嵌入式系统的电路。 许多电子设备中都有UVLO的功能,例如在镇流器中就有UVLO电路,若电压过低时直接切断电源。 UVLO就是低电压锁定; 低压关断. 欠压关断模式是当供电电压低于IC的开启门限电压时的一种保护模式。欠压关断模式可保证IC在供电电压不足时不致于被损坏。一个低电压锁定(

【深度学习】Progressive Distillation for Fast Sampling of Diffusion Models

这种方法通过迭代地将一个需要较多步骤的模型(称为教师模型)蒸馏成一个需要较少步骤的学生模型,每次迭代都将采样步骤减半,直到达到所需的采样步骤数量。通过渐进式蒸馏,论文将原始需要8192步采样的模型成功蒸馏为只需4步采样就能取得接近的生成质量的新模型,大幅提高了扩散模型的推理效率。这篇论文提出了一种"渐进式蒸馏"(Progressive Distillation)的方法,来大幅降低用于生成对抗网络(GAN)的扩散模型(Diffusion Model)在推理阶段的采样步数,从而提高其推理效率。
