嗯, 有这个问题.

```shell pip3 install -r requirements.txt ... Installing collected packages: MarkupSafe, zipp, Werkzeug, pycparser, Jinja2, itsdangerous, click, SQLAlchemy, six, parse, Mako, importlib-resources, importlib-metadata, Flask, cffi, WTForms, urllib3, pycryptodome, parse-type, idna, Flask-SQLAlchemy,...
看看是不是同类问题: https://github.com/Azure/azure-cli/issues/21363 https://github.com/heartexlabs/label-studio-ml-backend/issues/92 试试 Flask=1.1.4
在 `secret_settings.py` 配置中, 有这么一段: ``` SQLALCHEMY_ENGINE_OPTIONS = { 'pool_recycle': 3599, 'pool_size': 100 } ``` 让 `pool_recycle` 的值小于您 MySQL 中 `SHOW GLOBAL VARIABLES LIKE "wait_timeout";` 设置的值即可. 希望能帮到您. Ref: https://flask-sqlalchemy.palletsprojects.com/en/2.x/config/#timeouts
ths, 平时是根据各项目需求来扩展的, 每个项目涉及的功能不一样, 有共性或之后项目有大量复用的, 才会更新在这里面. 没有特意的做到功能全面, 基础框架在自由扩展更是初衷.
``` cornelk/hashmap alphadose/haxmap puzpuzpuz/xsync ``` 个人觉得都是些值得关注的 map 实现.
