+# Adapter `roberta-large-sst_pfeiffer` for roberta-large
+
+Adapter (with head) trained using the `run_glue.py` script with an extension that retains the best checkpoint (out of 30 epochs).
+
+
+**This adapter was created for usage with the [Adapters](https://github.com/Adapter-Hub/adapters) library.**
+
+## Usage
+
+First, install `adapters`:
+
+```
+pip install -U adapters
+```
+
+Now, the adapter can be loaded and activated like this:
+
+```python
+from adapters import AutoAdapterModel
+
+model = AutoAdapterModel.from_pretrained("roberta-large")
+adapter_name = model.load_adapter("AdapterHub/roberta-large-sst_pfeiffer")
+model.set_active_adapters(adapter_name)
+```
+
+## Architecture & Training
