怎么用tensorflow.js来预测价格？

当然可以

我来写一个例子

<script type="text/javascript" src="http://repo.bfw.wiki/bfwrepo/js/tf.min.js"></script>
<script type="text/javascript">

    async function predictfuture() {

        var xs = tf.tensor3d([
            [[1], [1], [0]],
            [[1], [1], [0]],
            [[1], [1], [0]],
            [[1], [1], [0]],
            [[1], [1], [0]],
            [[1], [1], [0]]
        ]);
        xs.print();

        var ys = tf.tensor3d([
            [[1], [1], [0]],
            [[1], [1], [0]],
            [[1], [1], [0]],

            [[1], [1], [0]],
            [[1], [1], [0]]
        ]);
        ys.print();


        ////////////////////////

    predictfuture();
