## Examples

Note that all examples here use the `cuda` and `cudnn` feature flags provided by the `candle-examples` crate. You may need to adjust them to match your environment.

```

Note that you have to specify the task with `--task=text-classification`. Furthermore, this particular model does not have `id2label` specified in the config.json file, so you have to provide them via the command line. You might have to dig around to find exactly what labels to use if they're not provided.
