【torch报错】RuntimeError: Unable to find a valid cuDNN algorithm to run convolution & realnet-优快云博客

realnet torch代码训练过程报错及解决

背景

在使用realnet的官方代码进行训练时报错如下，使用的命令为，采用了分布式DDP，不过本地只用了1张显卡：

python -m torch.distributed.launch --nproc_per_node=1  train_realnet.py --dataset VisA --class_name candle

网络参数等均采用的Visa下的realnet.yaml文件中的参数，本地显卡显存为24G，直接运行后出现这个错误
