在当前不可调试的 GPU 上创建了 CUDA 上下文
A CUDA context was created on a GPU that is not currently debuggable
当我启动 cuda 调试时，Nsight return 这个错误：
A CUDA context was created on a GPU that is not currently debuggable.
Breakpoints will be disabled.
Adapter: GeForce GT 720M
这是我的系统和CUDA信息。
请注意，已安装最新版本的 CUDA 和 Nsight。
我搜索了这个问题，但找不到我的答案。
非常感谢。

您的 GT 720m 是计算能力为 2.1 的设备（参见 here）。
尝试在同样支持（托管）显示器的 GPU 上调试 CUDA 代码（例如设置断点）需要计算能力为 3.5 或更高的设备，以支持 preemption。
您的设备不符合该要求，因此由于您的 GPU 正在托管您的笔记本电脑显示器，因此不能用于在 CUDA 代码中设置断点。
另请注意，最新版本的 Nsight VSE（此时为 5.2）具有 officially dropped support 用于 Fermi GPU（您的是 Fermi GPU）：
Note: Fermi family GPUs, and older families, are no longer supported with Nsight™ Visual Studio Edition 5.2 or better.
也许尝试回退到旧版本的 Nsight。
我最近 运行 遇到了这个问题，安装旧版本很有帮助。
当我启动 cuda 调试时，Nsight return 这个错误：
