python - reload如何处理库文件为 `so`

Question

我已经使用命令 pip --ignore-installed --user requests[security] 安装了一个用户模块，并意识到嵌入在工具中的 python 解释器忽略了该命令并首先加载系统范围内安装的模块 i:

/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/OpenSSL

因此，继续手动插入我的用户路径，并尝试重新加载 OpenSSL 中的每个模块，如下所示:

import sys
sys.path.insert(0, /Users/MYUSERNAME/Library/Python/2.7/lib/python/site-packages/)
reload(OpenSSL.SSL)
reload(OpenSSL.SSL)
reload(OpenSSL._util)
reload(OpenSSL.crypto)
reload(OpenSSL.rand)
reload(OpenSSL.version)

但是，我意识到 OpenSSL 附带 so 文件。 reload 是否也会重新加载 so 文件？

如果需要更多信息，请告诉我。

There are a number of other caveats:

It is legal though generally not very useful to reload built-in or dynamically loaded modules, except for sys, __main__ and builtins. In many cases, however, extension modules are not designed to be initialized more than once, and may fail in arbitrary ways when reloaded.
