Let's try to rerun the training with the batch script here: https://github.com/dmlc/gluon-nlp/tree/master/tools/batch#squad-training Basically, we just need to run the following two for SQuAD 2.0 and 1.1 |

Yes, you can later use the following script to sync up the results. After all results (part of the results) have been finished, you can parse the logs via |
