build_qa_database.py插数的时候有个小问题

[ShuGao0810]

数据量少于BULK_COUNT未执行插数，修改了一下：

def init_ES():
    pie = ProcessIntoES()
    # 创建ES的index
    pie.create_mapping()
    start_time = time.time()
    index = 0
    count = 0
    action_list = []
    BULK_COUNT = 1000  # 每BULK_COUNT个句子一起插入到ES中

    for line in open(pie.music_file, 'r', encoding='utf8'):
        if not line:
            continue
        item = json.loads(line)
        index += 1
        action = {
            "_index": pie._index,
            "_type": pie.doc_type,
            "_source": {
                "question": item['question'],
                "answers": '\n'.join(item['answers']),
            }
        }
        action_list.append(action)
        if index >= BULK_COUNT:
            pie.insert_data_bulk(action_list=action_list)
            index = 0
            count += 1
            print(count)
            action_list = []
            
    if index < BULK_COUNT:
        pie.insert_data_bulk(action_list=action_list)
    
    end_time = time.time()
    print("Time Cost:{0}".format(end_time - start_time))
