PyTorch GPU 与虚拟内存

接引前文《Windows 10 yolov5 GPU环境》,配置完成之后,一度因为虚拟内存没什么太大用处。原有设置的虚拟内存c盘(系统盘)为4096-8192。在我将虚拟内存改成1024-2048之后,然后tm报错了。就是上面的的这个错误:RuntimeError: Unable to find a valid cuDNN algorithm to run convolution。但是实际上,错误和cuda没有直接关系,目前我还不太清楚为什么虚拟内存直接关系到了cuda的运行环境,或者说pytorch的运行环境。网上搜了一下也没找到相关的资料,主要应该是我的理解太浅显。 

详细错误信息:

看到的不见得就是问题的关键,如果根据这个搜索可能解决不了问题。尝试将内存改回去。

1024是远远不够的,这个虚拟内存大小该根据什么来设置?如果不重启,直接再次运行然后就回报下面的错误:RuntimeError: CUDA out of memory. Tried to allocate 26.00 MiB (GPU 0; 10.00 GiB total capacity; 848.46 MiB already allocated; 7.01 GiB free; 892.00 MiB reserved in total by PyTorch)
