+This model is [Distilroberta base](https://huggingface.co/distilroberta-base) trained on SQuAD v2 as:
+
+```
+export SQUAD_DIR=../../squad2
+python3 run_squad.py 
+    --model_type robberta 
+    --model_name_or_path distilroberta-base 
+    --do_train 
+    --do_eval 
+    --overwrite_cache 
+    --do_lower_case 
+    --version_2_with_negative 
+    --save_steps 100000 
+    --train_file $SQUAD_DIR/train-v2.0.json 
+    --predict_file $SQUAD_DIR/dev-v2.0.json 
+    --per_gpu_train_batch_size 8 
+    --num_train_epochs 3 
+    --learning_rate 3e-5 
+    --max_seq_length 384 
+    --doc_stride 128 
+    --output_dir ./tmp/distilroberta_fine_tuned/
+```
+
+Performance on a dev subset is close to the original paper:
+
+```

+
+We are hopeful this might save you time, energy, and compute. Cheers!
