Question

我正在研究一些产生以下结果的KMeans代码。

    foreach ($barang as $item) {
        if ($mana_outstok <> '') {
            $pesan = 'The product is not enough!';
            $msg = [
                'validasi' =>  $pesan
            ];
            echo json_encode($msg);
        } else {
            $data = [
                'c_price' => $item['qty'] * $item['barang_harjul'],
                'qty' => $item['qty']
            ];

            // $cid = implode($c_cart_id);
            $where = [
                'c_cart_id' => $c_cart_id,
                'barang_id' => $item['barang_id']
            ];

            $this->db->where($where);
            $this->db->update('tbl_cart_detail', $data);
        }
    }

因此，在质心行上，出现此错误：

            e.preventDefault();
            $.ajax({
                url: "<?php echo base_url(); ?>toko/cart/updatecart",
                method: "POST",
                data: {
                    c_cart_id: c_cart_id,
                    barang_id: barang_id,
                    qty: qty,
                    barang_harjul: barang_harjul
                },
                success: function(data) {
                    if (data.validasi) {
                        Swal.fire({
                            icon: 'error',
                            title: 'Oops...',
                            text: $pesan,
                        });
                    } else {
                        console.log(data);
                    }

                }
            });
            // window.location.reload();

此外，当我查看数据时，也会看到以下内容：

# computing K-Means with K = 5 (5 clusters)
centroids,_ = kmeans(data,5)
# assign each sample to a cluster
idx,_ = vq(data,centroids)

这是所有金融股票数据。我的变量名为idx，我试图像这样绘制它。

cannot unpack non-iterable KMeans object

那给了我一个完全空白的情节。

所以，我这里有2个问题：

KMeans(algorithm='auto', copy_x=True,
       init=KMeans(algorithm='auto', copy_x=True, init=5, max_iter=300,
                   n_clusters=array([[ 1.16081512e-02,  2.85525825e-01],
