UnboundLocalError: local variable 'DOA_batch_pred_cart' referenced before assignment

Good evening!
How can I resolve the error below:

UnboundLocalError Traceback (most recent call last)

92 print('Test loss: {:.4f}, Test rmsae: {:.2f}deg'.format(loss_test, rmsae_test) )

Hello,

Did you make any changes to the code? Those line numbers don't seem to match the ones in the repository. I don't understand in which line the error happens since the one indicated the traceback doesn't use the variable DOA_batch_pred_cart and it's just a comment.
