[Hint: 'cudaErrorLaunchFailure'. An exception occurred on the device while executing a kernel. Common causes include dereferencing an invalid device pointerand accessing out of bounds shared memory. Less common cases can be system specific - more information about these cases canbe found in the system specific user guide. This leaves the process in an inconsistent state and any further CUDA work willreturn the same error. To continue using CUDA, the process must be terminated and relaunched.] (at ..\paddle\fluid\platform\gpu_info.cc:429)

我用了两个摄像头进行实时检测，但是跑一段时间后（几个小时或者几分钟）会报这个错误

windows不支持多线程读取数据哈
