Describe the bug
amr模型: MRP2020_AMR_ZHO_MENGZI_BASE

例1 输入 ["我", "不", "吃饭"]
执行结果中， 吃饭 对应的 "anchors": []

{
        "id": "0",
        "input": "我 不 吃饭",
        "nodes": [
            {
                "id": 0,
                "label": "我",
                "anchors": [
                    {
                        "from": 0,
                        "to": 1
                    }
                ]
            },
            {
                "id": 1,
                "label": "-",
                "anchors": [
                    {
                        "from": 2,
                        "to": 3
                    }
                ]
            },
            {
                "id": 2,
                "label": "吃饭-01",
                "anchors": []
            }
        ],
        "edges": [
            {
                "source": 2,
                "target": 1,
                "label": "polarity"

        "tops": [
            2
        ],
        "framework": "amr"
    }

例2， 输入 ["我", "吃饭"]
吃饭 对应的 "label": "死-01", "anchors": []

{
        "id": "0",
        "input": "我 吃饭",
        "nodes": [
            {
                "id": 0,
                "label": "我",
                "anchors": [
                    {
                        "from": 0,
                        "to": 1
                    }
                ]
            },
            {
                "id": 1,
                "label": "死-01",
                "anchors": []
            }
        ],
        "edges": [
            {
                "source": 1,
                "target": 0,

目前发现：加一个标点，则结果正常
输入: ["我", "吃饭", "。"]
输出:

{
        "id": "0",
        "input": "我 吃饭 。",
        "nodes": [
            {
                "id": 0,
                "label": "我",
                "anchors": [
                    {
                        "from": 0,
                        "to": 1
                    }

有意思。CAMR语料库可能还是太formal了。
