In Hacker's Delight, Second Edition, Hank Warren once again compiles an irresistible collection of programming hacks: timesaving techniques, algorithms, and tricks that help programmers build more elegant and efficient software, while also gaining deeper insights into their craft. Warren's hacks are eminently practical, but they're also intrinsically interesting, and sometimes unexpected, much like the solution to a great puzzle. They are, in a word, a delight to any programmer who is excited by the opportunity to improve. Extensive additions in this edition include * A new chapter on cyclic redundancy checking (CRC), including routines for the commonly used CRC-32 code * A new chapter on error correcting codes (ECC), including routines for the Hamming code * More coverage of integer division by constants, including methods using only shifts and adds * Computing remainders without computing a quotient * More coverage of population count and counting leading zeros * Array population count * New algorithms for compress and expand * An LRU algorithm * Floating-point to/from integer conversions * Approximate floating-point reciprocal square root routine * A gallery of graphs of discrete functions * Now with exercises and answers

网上的教程大多数是教大家如何加载自定义模型和函数，如下图 这个SelfAttention层是在训练过程自己定义的一个class，但如果要加载这个自定义层，需要在load_model里添加custom_objects字典，这个自定义的类，不要用import ，最好是直接复制进再训练的模型中，这些是基本教程。 ——————分割线讲重点—————— 如果直接运行上面的代码，会出现一个init初始化错误，如下图， 再来看看 这个SelfAttention 自定义的类的初始化 这就说明再调用这个类的时候，输入的ch=256并不会初始化这个类，需要先自定义好初始化值，如下图 调用方式不变 这样问
