The flask service started by gevent reports the error Too many open files
Traceback (most recent call last): File "/data/miniconda3/envs/ner_py37/lib/python3.7/site-packages/gevent/baseserver.py", line 227, in _do_read File "/data/miniconda3/envs/ner_py37/lib/python3.7/site-packages/gevent/server.py", line 198, in do_read OSError: [Errno 24] Too many open files 2022-07-13T12:23:52Z <WSGIServer at 0x7fc47ec6d790 fileno=4 address=0.0.0.0:8088> failed with OSError
This problem generally occurs when the interface is called frequently. This problem can be solved by modifying (change to a larger number) the limit of the number of times of reading and writing files in the Linux system.
