重新安装 PyTorch 之前，请先卸载所有已安装的 PyTorch。您可能需要多次运行pip uninstall torch。当您看到WARNING: Skipping torch as it is not installed时，表示torch已完全卸载。

You should only have topip uninstalla few times, but you can alwaysuninstallwithtimeoutor in a loop if you’re feeling lazy.
你只需要运行几次pip uninstall torch即可，但如果你懒得运行，也可以使用timeout或循环运行uninstall。

pip uninstall torch

Next runpython setup.py clean. After that, you can install in editable mode again.
接下来运行python setup.py clean。之后，你就可以再次以可编辑模式安装。

conda uninstall pytorch -y yes | pip uninstall torch

Uninstall all existing PyTorch installs:

conda uninstall pytorch pip uninstall torch pip uninstall torch # run this command twice
