只有一个GPU,不知道为啥会出现这个警告,给出的链接进去看了,让配置环境参量,但是不知道如何配置,网上查了下需要在程序里面配置gpu的代号,配置过了没有用,希望有人帮帮忙,谢谢
警告:Unified Memory Profiling is not supported on the current configuration because a pair of devices without peer-to-peer support is detected on this multi-GPU setup. When peer mappings are not available, system falls back to using zero-copy memory. It can cause kernels, which access unified memory, to run slower.
