报错：no suitable user-defined conversion from "CudaAllocator<int>" to "CudaAllocator<std::_Container_proxy>" exists

在08课程04_sugar\01下面生成 visual studio 2022 项目之后，运行报错如下： “no suitable user-defined conversion from "CudaAllocator" to "CudaAllocator" exists”，请问老师如何修改？

已经修复 https://github.com/parallel101/course/blob/master/08/include/CudaAllocator.h#L28C1-L34C6

[archibate]

    template <class U> // cihou shabi wendous
    constexpr CudaAllocator(CudaAllocator<U> const &other) noexcept {
    }

    constexpr bool operator==(CudaAllocator<T> const &other) const {
        return this == &other;
    }

@archibate 小彭老师，我试验了一下，好像没有效果，仍然保一样的错。
