Method view

include/pybind11/numpy.h:1307–1315

Create a view of an array in a different data type. This function may fundamentally reinterpret the data in the array. It is the responsibility of the caller to ensure that this is safe. Only supports the `dtype` argument, the `type` argument is omitted, to be added as needed.

    /// Only supports the `dtype` argument, the `type` argument is omitted,
    /// to be added as needed.
    array view(const std::string &dtype) {
        auto &api = detail::npy_api::get();
        auto new_view = reinterpret_steal<array>(api.PyArray_View_(
            m_ptr, dtype::from_args(pybind11::str(dtype)).release().ptr(), nullptr));
        if (!new_view) {
            throw error_already_set();
        }
        return new_view;
    }

    /// Ensure that the argument is a NumPy array
    /// In case of an error, nullptr is returned and the Python error is cleared.
