该cell的代码改为如下代码可避免报错： X, y = iter(test_iter).next() true_labels = d2l.get_fashion_mnist_labels(y.detach().numpy()) pred_labels = d2l.get_fashion_mnist_labels(net(X).argmax(dim=1).detach().numpy()) titles = [true + '\n' + pred for true, pred in zip(true_labels, pred_labels)] d2l.show_fashion_mnist(X[0:9], titles[0:9])
