初始化 superset 数据库时失败，执行superset db upgrade报错：
(superset) [diyizu@diyizu12 ~]$ superset db upgrade

Therefore, support for it is deprecated in cryptography. The next release of cryptography (40.0) will be the last to support Python 3.6.

ModuleNotFoundError: No module named 'cryptography.hazmat.backends.openssl.x509'
ModuleNotFoundError:没有名为“cryptography.hazmat.backends.openssl.x509”的模块
分析：因为cryptography模块陈旧，
思路：
python -m pip uninstall cryptography
python -m pip install cryptography
这个我也经历过，这是因为cryptography模块陈旧，恢复办法是
python -m pip uninstall cryptography
python -m pip install cryptography
大功告成！望采纳
看日志很关键哈

import cryptography
确实是cryptography跟python版本不对应的问题。
安装superset（详细版）
跟着步骤走

有几种可能的解决方法：
1.重新安装 cryptography 库，确保安装了正确的版本。
2.尝试使用其他版本的 Python 运行 superset db upgrade 命令，看看是否能正常执行。
3.检查 superset 环境中是否有其他库与 cryptography 冲突，尝试删除冲突的库。
