Django uses some python magic to define relationships between models, some of which involves using the name of the models in the relationships (that’s where the ‘test’ in ‘test__set’ is coming from.) What’s happening, I would guess, is that it’s trying to put “test__set” in the Example model twice, once for each foreign key you’ve got defined.
The error message suggests something to try: define a related_name argument (overriding one of those ‘test_set’s) that it can use instead of auto-generating two clashing names.

Try using related_name:
class Test(models.model):
example1 = models.ForeignKey('Example', related_name='example1')
example2 = models.ForeignKey('Example', related_name='example2')

Just do what the error message tells you to do, and if you’re unsure what that means, consult the documentation for related_name.

In django 2.0 Try this:
user = models.ForeignKey(User, on_delete=models.PROTECT, null=True, related_name='user')
paper = models.ForeignKey(paperRecord, on_delete=models.PROTECT, null=True, related_name='paper')
