import resource_rc

mas está causando erro como abaixo.

ImportError: nenhum módulo chamado 'resource_rc'

Eu já tentei encontrar esse erro no StackOverflow, mas ninguém conseguiu esse erro.

Estou usando o Python 3.5 e o PyQt 5.6. (Eu sei que o PyQt é incompatível com o Python 3.5, mas não tenho nenhum erro, exceto isso)

Agora, o código está funcionando sem nenhum problema depois que eu removi a última linha de códigos: 'import resource_rc'

mas exatamente o que essa linha está fazendo?

(desculpe pelo meu péssimo inglês)
