欢迎您反馈PaddleHub使用问题，非常感谢您对PaddleHub的贡献！ 在留下您的问题时，辛苦您同步提供如下信息：

• 版本、环境信息 1）PaddleHub和PaddlePaddle版本：请提供您的PaddleHub和PaddlePaddle版本号，例如PaddleHub1.4.1，PaddlePaddle1.6.2 2）系统环境：请您描述系统类型，例如Linux/Windows/MacOS/，python版本
• 复现信息：如为报错，请给出复现环境、复现步骤 paddlehub1.7.1 paddlepaddle-gpu 1.8.2 linux18.04 2080显卡4块，然后cuda cudnn nccl已经正确安装，在跑paddlepaddle-gpu的测试代码时，提示信息如下：

Your Paddle Fluid is installed successfully! Let's start deep Learning with Paddle Fluid now 可是在运行口罩检测模型时，设置环境变量如下： os.environ['CUDA_VISIBLE_DEVICES'] = '0'或者os.environ['CUDA_VISIBLE_DEVICES'] = '0，1，2，3' 运行均会报错：

Error Message Summary:

ExternalError: Cuda error(3), initialization error. [Advise: The API call failed because the CUDA driver and runtime could not be initialized. ] at (/paddle/paddle/fluid/platform/gpu_info.cc:183) 求帮助！
