[Question]: uie 多进程？

[yifeizhou980429]

请提出你的问题

uie运行多进程报错问题，paddlenlp ==2.4.0 paddlepaddle == 2.3.2 python ==3.6.8 ，跑多进程（10个，100个） if "relations" not in relations[k][i].keys(): 这一行会报错keyerror，这是什么原因啊？

UIE使用多进程的是需要加锁的，

from flask import request, jsonify, Flask
from src.parser import DocParser
import threading
lock = threading.Lock()
server = Flask(__name__)

# 调用uie模型
parser = DocParser(model_path_prefix="src/uie/export/building/inference")


@server.route('/docParser', methods=['get', 'post'])
def parser_server():
    file = request.files.get('file')  # 接受上传文件
    lock.acquire()
    result = parser.parser_passage(file)
    if isinstance(result, dict):
        lock.release()
        return jsonify(result), 200
    else:
        lock.release()
        return jsonify({"msg": result}), 500


if __name__ == '__main__':
    server.run(port=9092, host='0.0.0.0', debug=False, threaded=True)

为什么要加锁？
