I just solved this problem,when i user WORKER_CLASS = 'gevent' or WORKER_CLASS= 'uvicorn.workers.UvicornWorker',it can't wok,

Comment out WORKER_CLASS in gunicorn.py, it [works]

[zhoupan163]

I use sw-python run -p gunicorn gunicorn.py -D ppt_service.main:app,to start my service, I find the code from gevent import monkey monkey.patch_all() in gunicorn.py,it can not work, delete the code from gevent import monkey monkey.patch_all(),it works fine,This error has nothing to do with work class
