无法使用gpu训练

[Tingting-Liu-star]

python main.py -m KGCN -d LastFM4KGCN -t recommendation -g 0 --use_best_config

RuntimeError: Tensor for argument #2 'mat1' is on CPU, but expected it to be on GPU (while checking arguments for addmm)

我这边尝试跑了一遍，没有出现您所说的这个问题，能否提供更多的报错信息好让我们处理这个问题？

我也尝试运行了一遍，并没有复现出这个bug，请问您是否按照我们提供的安装步骤完成或者有修改过代码吗

感谢，我重新配置了环境，问题已解决
