Some dependencies of `huggingface_hub` are [optional](https://setuptools.pypa.io/en/latest/userguide/dependency_management.html#optional-dependencies) because they are not required to run the core features of `huggingface_hub`. However, some features of the `huggingface_hub` may not be available if the optional dependencies aren't installed.  
You can install optional dependencies via `pip`:
