Deforum_Stable_Diffusionで RuntimeError: PytorchStreamReader failed reading zip archive: failed finding central directory

Posted at

Deforum_Stable_Diffusionやってると, RuntimeError: PytorchStreamReader failed reading zip archive: failed finding central directory とか言われることがあって,その際の対処方法のメモです.エラー内容は↓.

reading custom settings from /content/drive/MyDrive/Settings.txt
The custom settings file does not exist. The in-notebook settings will be used instead
Saving animation frames to /content/drive/MyDrive/AI/StableDiffusion/2022-12/StableFun
Loading base model ()...Using cache found in /root/.cache/torch/hub/rwightman_gen-efficientnet-pytorch_master
Done.
Removing last two layers (global_pool & classifier).
Building Encoder-Decoder model..Done.

解決方法

自分の場合は色々試したあげるく,Google colabのファイルを作り直すことで解決しました.

Pytorchの何かしらのzipファイルを読み込む失敗のエラーだと思うので,dpt_large-midas-2f21e586.pt を手動でとってきたり色々試しり,StackOverflowに書かれていたように,ドライブにあるAIフォルダを削除するも試したのですが,すべてダメで,Colabファイル作り直すのが良いと思います.
