别慌,仔细看看 rand.Intn(10) * 1000 和 1000 的区别在于:前者是变量,类型已经确定了,通不过编译是情理之中;而后者是常量,类型并不是 int ,属于 untyped constants...WTF,Go… 参考: https://go.dev/blog/constants (本文主要搬运来源) https://blog.learngoprogramming.com/learn-golang-typed-untyped-constants
根据官网的帮助文档,介绍Constants类型的函数,方便自己学习和查看。若是有幸帮到别的朋友,深感荣幸。
注意: start 和 stop 参数都必须是 浮点型; 取值范围也包括了 stop; tf.lin_space 等同于 tf.lins...
