How to create a dataset for SASRec, SSE-PT and BERT4Rec from the database dump?

To train all the models, use the following command to create a dataset file from the database dump:

psql -c "select studente, esame, voto from supera order by studente, datasup" -e dataset_students -t -F " " -A -E > dataset.txt

With this command, a dataset.txt file will be generated with the following format:

student_id exam_id grade

Exams are sorted by student_id and date, with the latter being implicit since we solely require the exam sequence for each student.
