解決上述問題：

1. CUDA版本查詢：支持的版本與Nvidia驅(qū)動(dòng)有關(guān)

nvidia-smi

????nvcc-v

2. torch環(huán)境沖突

conda uninstall pytorch

pip uninstall pytorch

pip uninstall torchvision

pip uninstall torchaudio

3. 卸載后

conda clean -a

4. 重新安裝pytorch

pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu118

5.問題解決
