我在构建模型时收到警告——一开始我不认为这是真的;也许事情已经改变了:
模型:
# Initialise Sequential model
regressor = Sequential()
# units is the output dimensionality
# return sequences will return the sequence
# which will be required to the next LSTM
# as a great big rule-o-thumb, layers should be less than 10, and perhaps 1 per endog plus 1 for all exog

Run Code Online (Sandbox Code Playgroud) 我有一个数组var mya = ["someval1", "someotherval1", "someval2", "someval3"];,我有一个函数接收一个属性设置为其中一个名称的对象.
迭代数组是有意义的,并检查每个数组是否可以在数组中找到它,就像在for语句中一样.但switch在这种情况下,似乎更有效的方法会使用语句,因为数组是静态的,当我找到属性时的任务取决于找到的属性.
如何使用开关阵列执行此操作?像这样的伪代码:
switch(mya.forEach) {
case "someval1":
alert("someval1");
break;
...
default:
alert("default");
break;
}

但这只召唤一次.
给出的答案都是我已经拥有的代码 - 我猜有没有更清晰的foreach配方switch.
这里可能有几个小的样式问题,但大多数情况下是有效的。但是,它似乎并没有监视styles/*.scss该文件夹中文件或新 SCSS 的更改。与 Javascript 相同:scripts/*.js不在手表上更新。
也可以在不破坏源映射的情况下结合 SCSS 和 CSS,但这并不重要。现在,只要让实时更新工作就好了。

我有一个 .net-core 3.1 解决方案,其简单端点仅接受帖子。我想使用 openAPI-generator 生成 SDK(因为Visual Studio for mac中不提供 New REST Client SDK 选项)。

这生成了一个 .net 框架解决方案,因此我必须对其进行一些修改并安装一些 nuget 测试库才能使其运行。毕竟我的连接被拒绝了——我希望这只是因为它是为错误的框架构建的。
