+Work by [Frederico Vicente](https://huggingface.co/mrvicente) & [Diogo Tavares](https://huggingface.co/d-c-t). We finetuned BART Large for the task of generative question answering. It was trained on eli5, askScience and stackexchange using the following forums: pets, cooking, gardening, diy, crafts. 
+
+### Usage
+
+```python
+
+from transformers import (
+      BartForConditionalGeneration,
+      BartTokenizer
+)
+import torch
+import json
+
+def read_json_file_2_dict(filename, store_dir='.'):
+    with open(f'{store_dir}/{filename}', 'r', encoding='utf-8') as file:
+        return json.load(file)
+
+def get_device():
+    # If there's a GPU available...
+    if torch.cuda.is_available():
+        device = torch.device("cuda")
+        n_gpus = torch.cuda.device_count()
+        first_gpu = torch.cuda.get_device_name(0)
+
+        print(f'There are {n_gpus} GPU(s) available.')
+        print(f'GPU gonna be used: {first_gpu}')
+    else:
+        print('No GPU available, using the CPU instead.')
+        device = torch.device("cpu")
+    return device
