如何以角度4进行多个订阅？

Question

如何在以角度获取数据后执行多个订阅并执行常见操作？

myfunction() {

    this.service1.function1.subscribe((data) => {
        console.log("get this first");

        this.service2.function2.subscribe((data) => {
            console.log("get this second");

            this.service3.function3.subscribe((data) => {
                console.log("get this third");
            }

    if(first && second && third){
        dosomeoperations;
    }

我知道如上所述做错了。如何以适当的方式做到这一点，角度我是新的角度。任何帮助将不胜感激！

Answer 1

您可以使用 alpha_cost = 2 cost = tf.reduce_mean(tf.where(tf.less(Y * out, 0), tf.squeeze((alpha_cost*out)**2 - tf.sign(Y)*out + tf.abs(Y)), tf.squeeze(tf.abs(Y - out))))运算符
