## `src/transformers/utils/hub.py` — `function:download_url` (lines 561-584)
```python
def download_url(url, proxies=None):
"""
Downloads a given url in a temporary file. This function is not safe to use in multiple processes. Its only use is
for deprecated behavior allowing to download config/models with a single url instead of using the Hub.
Args:
url (`str`): The url of the file to download.
proxies (`Dict[str, str]`, *optional*):
A dictionary of proxy servers to use by protocol or endpoint, e.g., `{'http': 'foo.bar:3128',
'http://hostname': 'foo.bar:4012'}.` The proxies are used on each request.
Returns:
`str`: The location of the temporary file where the url was downloaded.
"""
warnings.warn(
f"Using `from_pretrained` with the url of a file (here {url}) is deprecated and won't be possible anymore in"
" v5 of Transformers. You should host your file on the Hub (hf.co) instead and use the repository ID. Note"
" that this is not compatible with the caching system (your file will be downloaded at each execution) or"
" multiple processes (each process will download the file in a different temporary file)."
