a correction

I think the 3 lines in train_classification.py:

        class_acc[cat, 0] += classacc.item() / float(points[target == cat].size()[0])
        class_acc[cat, 1] += 1

shoud be replaced by:

        class_acc[cat, 0] += classacc.item()
        class_acc[cat, 1] += float(points[target == cat].size()[0])

This will match the code below：

        class_acc[:, 2] = class_acc[:, 0] / class_acc[:, 1]
        class_acc = np.mean(class_acc[:, 2])
