PyCharm调试器附加到本地进程但不会暂停

Question

我有一个长期运行的Python 3.5进程已挂起。我跟着https://www.jetbrains.com/help/pycharm/attaching-to-local-process.html加入了这个过程。

我已成功附加到流程

Attaching to a process with PID=4332
C:\Python35\python3.exe "C:\Program Files\JetBrains\PyCharm Community Edition 2017.2\helpers\pydev\pydevd_attach_to_process\attach_pydevd.py" --port 13980 --pid 4332
Connected to pydev debugger (build 172.3317.103)
Attach finished successfully.

但是当我按下PyCharm调试器暂停按钮来检查状态时没有任何反应。
