The reason why the logic for creating an object is put into a separate class is that it can be used by multiple clients. And separates the creation and use of objects. However, this design also has many defects. First of all, SimpleFactory is a specific class, so we must program for the implementation, making the system lose its flexibility in this respect. Second, if we add new products, we have to modify the code in SimpleFactory, which violates the opening and closing principle. The above model is also called simple factory. He does not appear in GOF mode, it is more like a programming habit.伦文叙和同学们在这个危机四伏却又充满温馨的校园内一起学习和生活，一起经历风雨和彩虹，演绎了一出出搞怪爆笑的现代校园喜剧。2248年，休眠的C40小队队长方毅（任天野 饰）和他的小队成员刘火（王韬 饰）、段依山（程汉 饰演）等被人工智能控制系统长夜之光唤醒，并将执行一项绝密任务——潜入基因药物研究中心，销毁所有药物及试验资料。而研究中心已经遭到Mr.Dee（丁海峰 饰）带领的黑羽会入侵，为了获得延长休眠的权限，C40小队必须接受这场生死行动……喂鸡的时候，那鸡还你啄我一下，我戳你一口哩。本剧改编自HarlanCoben在2012年出版的同名《纽约时报》畅销小说。Coben将和领头编剧DannyBrocklehurst,及RichardFee共同负责8集剧本,DanielO’Hara担任领头导演。这是Netflix和HarlanCoben的5年14本书超级合约下进行的第5个项目。跟随之前的合作项目,本剧将设定在英国。故事聚焦三个生活安好的人,每个人都有不可告人的秘密,而身边最亲近的人都不会对此产生怀疑。Megan(Jumbo),一名有三个孩子的职业母亲；Ray(Armitage),曾经未来光明的纪录片摄影师,如今干着一份没有前途的工作,迎合那些痴迷明星的有钱人家孩子；Broome(Nesbitt),一名侦探,放不下一桩失踪人口悬案。Lorraine(Parish),来自Megan过去的一位老朋友,带来了一些惊人的...Super Data Manipulator: I am still groping at this stage. I can't give too much advice. I can only give a little experience summarized so far: try to expand the data and see how to deal with it faster and better. Faster-How should distributed mechanisms be trained? Model Parallelism or Data Parallelism? How to reduce the network delay and IO time between machines between multiple machines and multiple cards is a problem to be considered. Better-how to ensure that the loss of accuracy is minimized while increasing the speed? How to change can improve the accuracy and MAP of the model is also worth thinking about.为了生计，心蕾不得不开始工作，期间受到了很多的委屈。心蕾把新认识的富家子孔彦祥作为了依靠的对象。秦朗渐渐对心蕾产生了感情，而往日的未婚夫尚东也找到了心蕾。秦朗只好将自己的感情藏于心底……
