在这个示例中,modify_numpy_array函数接受一个py::array_t<double>类型的参数,表示一个双精度浮点数的NumPy数组。函数通过py::buffer_info获取数组的指针,并遍历数组,将每个元素乘以2。然后,使用PYBIND11_MODULE宏定义一个Python模块,并将modify_numpy_array函数暴露给Python使用。 5. 指出可能遇到的问题以及...

pybind11 can automatically vectorize functions so that they are transparently applied to all entries of one or more NumPy array arguments. (对于 np.ndarray数组,pybind 接口能自动向量化) Python's slice-based access and assignment operations can be supported with just a few lines of code. (对于 Py...
