Até a aula anterior o código estava rodando lindamente, consegui adicionar alunos e cursos pelo admin no navegador. Depois dessa aula, começou a aparecer esse erro.

Uso essa importação from RestAPI.escola.models import Aluno, Curso mas porque se eu não usasse a pasta RestAPI (onde esta a escola) dava ruim. Alguém pode me ajudar, por favor?
