Try set **/home/user/huggingface** or so to **HF\_HOME** env.
It seems that the directories beginning with a dot in the Hugging Face Spaces become read-only, but Transoformers and other programs try to write to the cache there. I think this is a bug in the broad sense, but I don’t know where to report it…😭 perhaps @Wauplin ?
I think you can avoid this by changing the cache folder using the method above.

you mean to set os.environ[HF\_home]

If you can do that before Transoformers starts, that’s fine too, and you can set the environment variables and Secrets environment variables from the Settings in Spaces.
```auto
import os
os.environ["HF_HOME"] = "/home/user/huggingface"
```

You can also do that directly in your Dockerfile:
```auto
ENV PYTHONUNBUFFERED=1 \
PORT=8000 \
HF_HOME=/home/user/huggingface
```
