Issue description When pybind11 casts from python->C++ for a function call, the casters for each argument are kept alive for the duration of the function call. This is important when passing a pointer or reference to memory owned by the ...
使用函数指针:如果函数签名不兼容是由于返回类型不匹配导致的,可以考虑使用函数指针的方式来解决。在pybind11中,可以使用PYBIND11_DECLARE_HOLDER_TYPE宏来声明函数指针的返回类型。通过定义一个返回函数指针的函数,可以在Python中获取函数指针,并进行相应的操作。
python和C++对于管理内存和对象的生存时间非常不同。这样当在C++和python之间创建binding的时候，如果function返回的类型是a non-trivial type. 只通过类型信息，python无法确定是否管理返回的value并释放其资源，无法确定其是否在C++侧进行处理。

我发现了错误：我使用的是Eigen::Map而不是Eigen::Ref。
mypy Pyrightfrom Microsoft, pytypefrom Google, Pyrefrom Facebook. Pylint3.0 can also use pyi files. The plan is to evaluate at least some of the tools above and include type stubs in the next release (while still using pybind11).
