2. 理解torch.backends.cudnn.enabled返回true的含义 torch.backends.cudnn.enabled 返回true 表示PyTorch 试图启用 cuDNN 加速。然而,由于 CUDA 不可用,这个设置实际上不会影响执行。cuDNN 是 CUDA 深度神经网络库的一个扩展,它专门用于加速深度神经网络。 3. 检查CUDA驱动和运行时是否已正确安装 您可以通过以下步...

cuDNN使用非确定性算法,并且可以使用torch.backends.cudnn.enabled = False来进行禁用 如果设置为torch.backends.cudnn.enabled =True,说明设置为使用使用非确定性算法 然后再设置: torch.backends.cudnn.benchmark = true 1. 那么cuDNN使用的非确定性算法就会自动寻找最适合当前配置的高效算法,来达到优化运行效率的...
