针对你提供的命令 python -c "import torch; print(torch.cuda.is_available())" 返回False 的问题,我们可以从以下几个方面进行分析和解答: 1. 为什么 torch.cuda.is_available() 返回False? torch.cuda.is_available() 返回False 通常意味着 PyTorch 无法检测到可用的 CUDA 设备,这可能是由于以下几个原因: ...

我们再来看看GPU驱动和CUDA是否能用: importtorchprint(torch.cuda.is_available()) 控制台打印显示True,则说明能正常使用。 引用参考 https://pytorch.org/get-started/locally/ https://blog.csdn.net/wgx571859177/article/details/78273764
