|
* If you want to download a protected model (one gated behind accepting a license or otherwise private, like `bigcode/starcoder`) you can set the environment variables `HF_USER` to your huggingface username and `HF_PASS` to your password or (_as a better option_) to a [User Access Token](https://huggingface.co/settings/tokens). Note that you will need to accept the model terms on the Hugging Face website before starting the download.
