• Requires Python >= 3.8 and PyTorch >= 1.11
• conda list torch 查看包 pip uninstall torch 及各个包，nvidia-smi查看cuda11.4，安装对应11.3
• 去官网找cuda11.3和torch1.11.0并粘贴命令，再安装torcheval

pip install torch1.11.0+cu113 torchvision0.12.0+cu113 torchaudio==0.11.0 --extra-index-url https://download.pytorch.org/whl/cu113

pip install torcheval
