报错的pdf文件在单线程会触发这个问题吗？

[myhloli]

最近的版本修改了magic_pdf/model/pdf_extract_kit.py和magic_pdf/model/pek_sub_modules/self_modify.py的一些代码，看了你的报错，代码行数和最新的版本对不上，可以尝试更新到最新版本再进行测试

[georgewangchn]

我也碰到了这个问题,并发请求8个报错，并发请求4个不报错。
paddlepaddle-gpu 2.6.2
paddleocr 2.8.1

[myhloli]

paddleocr不支持多线程导致的，请尽量使用多进程而不是多线程来处理并发。
