I have a Gradio app in a Space. Its first action is:

```auto
self.dataset = load_dataset(dataset_name)
self.dataset = self.dataset.cast_column("audio", Audio(sampling_rate=16000))

```

I’ve added persistent storage to my Space, but every time I restart the app with a git push, it spends several minutes reloading the dataset. It doesn’t seem to be caching it at all. What am I missing?

Thanks!

hi @danavery ,

In order to use the persistent storage to cache the dataset, you have to set the `huggingface_hub` cache folder to `/data`.

got to: `https://huggingface.co/spaces/...../settings`  
Set Variable

`HF_HOME` to `/data/.huggingface`

Thank you!  
I had wrongly assumed it would use the default cache path somehow, but it’s helpful to know that it doesn’t.
