首先,这个错误提示是告诉你,PyTorch在CUDA运行时遇到了一个错误,但是这个错误信息并没有直接显示出来。为了查看具体的错误信息,你可以设置环境变量CUDA_LAUNCH_BLOCKING=1,这样可以让CUDA运行在同步模式下,从而在发生错误时能够停止程序并显示详细的错误信息。你可以在运行PyTorch程序之前设置这个环境变量,如下所示:在Linux...
1. 理解CUDA_LAUNCH_BLOCKING=1的含义和作用 CUDA_LAUNCH_BLOCKING=1是一个环境变量,用于控制CUDA内核(kernel)的启动行为。默认情况下,CUDA内核的启动是异步的,这意味着当CPU(host)启动一个CUDA内核后,它会立即继续执行下一条指令,而不会等待CUDA内核在GPU(device)上完成。这种异步性可以提高程序的并行效率,但也会...
确认您正在使用的CUDA版本与安装在系统上的驱动程序和CUDA工具包兼容。您可以参考官方文档进行检查:https://docs.nvidia.com/cuda/cuda-toolkit-release-notes/index.html 尝试将环境变量CUDA_LAUNCH_BLOCKING设置为1,以使CUDA运行时等待所有内核执行完成后再返回结果。这样做可能会降低性能,但有助于确定代码中出现问题...
