# create a Series from a dict
pd.Series({key: value for key, value in zip('abcdef', range(6))})

uswgi - 无法从 multiprocessing.semaphore_tracker 加载配置

目前我正在将 Flask 应用程序部署到 Ubuntu 服务器 (AWS)。当我尝试启动 uwsgi 服务器并使用 journalctl 查看日志时,我注意到一种警告/错误。

我可以忽略它吗?我不知道如何解决它或它来自哪里。现在坚持了2天。谁能帮我?

错误:

 *** Operational MODE: preforking ***
