Anaconda: 清理沒有被使用的 packages

使用 TreeSize 觀察 disk 空間花在哪些地方，發現舊版的 pytorch packages 佔據不少空間:



使用 conda clean -p 清理沒有被使用的 packages:

(base) PS C:\Users\murph> conda clean -p
WARNING: C:\Users\murph\.conda\pkgs does not exist
WARNING: C:\Users\murph\AppData\Local\conda\conda\pkgs does not exist
Cache location: C:\Develop\anaconda3\pkgs
Will remove the following packages:
