requests.exceptions.ConnectionError: ('Connection aborted.', RemoteDisconnected('Remote end closed connection without response'))如果使用：hub serving start --modules ocr_system==1.0.0 --port 8866
进行启动服务就无法并发，但是对于出现以上情况的图片有响应结果

你好，使用并发启动服务会报错，但是有响应结果吗？

没有响应结果，报错后程序直接退出。

你好，hub的预训练模型库里好像没有ocr_system这个模块诶，这个是你自己实现的么？

https://github.com/PaddlePaddle/PaddleOCR/blob/release/2.6/deploy/hubserving/readme.md 我是使用这个文档进行部署的，ocr_system在这里面有。

好的，我这边跟着复现一下试试。同时，你也可以在PaddleOCR提个issue,这个模块他们开发的可能能比我更快地给你提供帮助。

PaddleHub无法通过多线程来加速模型预测，因为PaddlePaddle自身的限制。如果您需要更多关于PaddleHub的信息，可以访问PaddleHub的官方网站。
