Question

我首先将时间转换为正确的格式，代码工作正常我在创建数据框时遇到问题，无法解决问题该代码可以正常工作：

from datetime import datetime as dt


def convert_ts(hit):
    hit = hit['_source']
# change Refill_Bar_End_Date_and_Time
    try:
        ts_from_doc = hit.get('End_Date', None)

        if not ts_from_doc:
            raise ValueError('`End_Date` not found')

        # incoming as millisec so convert to sec
        as_date = dt.fromtimestamp(
            int(ts_from_doc / 1000.0)
        ).strftime('%Y-%m-%d %H:%M:%S')

        hit['End_Date'] = as_date

    except Exception as e:
        print(e)
        pass
    return hit

es = Elasticsearch(['http://localhost:9200'], timeout=600)
documents = es.search(index='sub1', body={})['hits']['hits']
documents = [convert_ts(doc) for doc in documents]

print(documents)

通过这个，我试图从我已经处理过的“文档”中创建数据框

from elasticsearch import Elasticsearch
from pandasticsearch import Select
# Convert the result to Pandas Dataframe
pandas_df = Select.from_dict(documents).to_pandas()

我有错误
