I wonder how Hugging Face is running Docker Spaces. [My space](https://huggingface.co/spaces/AlphaSphereDotAI/Chattr/tree/a56ea508a7184a40b37b231762d44a2b432e896a) is working fine, but Hugging Face gives me a runtime error

```bash
===== Application Startup at 2025-08-10 15:41:44 =====

Fatal Python error: Failed to import encodings module

ModuleNotFoundError: No module named 'encodings'

`Dockerfile` for Hugging Face’s Docker Space [requires some tricks in terms of permissions, paths and other settings](https://huggingface.co/docs/hub/spaces-sdks-docker).  
In any case, it [may be safer not to hardcode `PYTHONHOME`](https://stackoverflow.com/questions/38132755/importerror-no-module-named-encodings).
