我也遇到了这个问题，不知道您现在是否解决了，还请不吝赐教

这个问题我也遇到了。我是这么解决的： 首先我这边出现这个问题的原因是运行代码后报错，报错信息为zip() 没有len属性。定位错误发生在filternyt.py文件的25、28行。这是python2->python3的原因。将其修改为：

def __init__(self, root_path, train=True):
    if train:
        path = os.path.join(root_path, 'train/')
        print('loading train data')
    else:
        path = os.path.join(root_path, 'test/')
        print('loading test data')

    self.labels = np.load(path + 'labels.npy')
    self.x = np.load(path + 'bags_feature.npy')
    self.x = zip(self.x, self.labels)

    print('loading finish')

def __getitem__(self, idx):
    assert idx < len(list(self.x))
    return self.x[idx]

def __len__(self):
    return len(list(self.x))

然后就出现了如下错误：

IndexError: list index out of range

查找原因为，zip类似为迭代指针，使用一次后会自动释放。因此应该如此修改代码：

def __init__(self, root_path, train=True):
    if train:
        path = os.path.join(root_path, 'train/')
        print('loading train data')
    else:
        path = os.path.join(root_path, 'test/')
        print('loading test data')

    self.labels = np.load(path + 'labels.npy')
    self.x = np.load(path + 'bags_feature.npy')
    self.x = list(zip(self.x, self.labels))

    print('loading finish')

def __getitem__(self, idx):
    assert idx < len(self.x)
    return self.x[idx]

def __len__(self):
    return len(self.x)
