so, then sys.modules[name].__spec__ is returned. If that happens to be
set to None, then ValueError is raised. If the module is not in
sys.modules, then sys.meta_path is searched for a suitable spec with the
value of 'path' given to the finders. None is returned if no spec could
be found.
Dotted names do not have their parent packages implicitly imported. You will
most likely need to explicitly import all parent packages in the proper
order for a submodule to get the correct spec.

If the name is for submodule (contains a dot), the parent module is
automatically imported.
The name and package arguments work the same as importlib.import_module().
In other words, relative module names (with leading dots) work.

g) +_incompatible_extension_module_restrictionsw a A context manager that can temporarily skip the compatibility check.
NOTE: This function is meant to accommodate an unusual case; one
which is likely to eventually go away. There's is a pretty good
chance this is not what you were looking for.
WARNING: Using this function to disable the check can lead to
unexpected behavior and even crashes. It should only be used during
extension module development.
If "disable_check" is True then the compatibility check will not
happen while the context manager is active. Otherwise the check
*will* happen.
Normally, extensions that do not support multiple interpreters
may not be imported in a subinterpreter. That implies modules
that do not implement multi-phase init or that explicitly of out.
Likewise for modules import in a subinterpreter with its own GIL
when the extension does not support a per-interpreter GIL. This
implies the module does not have a Py_mod_multiple_interpreters slot
set to Py_MOD_PER_INTERPRETER_GIL_SUPPORTED.
In both cases, this context manager may be used to temporarily
disable the check for compatible extension modules.
You can get the same effect as this function by implementing the
basic interface of multi-phase init (PEP 489) and lying about
support for multiple interpreters (or per-interpreter GIL).
