Foreword:
This is the error reported by the blogger when running the code when installing torch v1.8.2 with LTS support.
1. Version Description
The methods on the Internet say that this is a version mismatch, but the version number given by the torch official website matches.
torch=1.8.2
torchaudio=0.8.2
torchvision=0.13.1
2. Problem solving
Use the mouse to click on the file where pycharm reports the error and click in (ctrl+left-click).
Just delete the ao in the middle
3. Attention
If you try to install other versions of torchaudio, the currently dependent pytorch will also be deleted.
