This model is ALBERT base v2 trained on SQuAD v2 as:

python run_squad.py 
--model_type albert 
--model_name_or_path albert-base-v2 
--do_train --do_eval 
--do_lower_case 
--version_2_with_negative 
--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/albert_base_fine/

Performance on a dev subset is close to the original paper:

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