训练到第23个epoch中止，无法正常运行

报错内容

看不出问题代码是哪部分，因为是dataset_iterator_kernel的问题，请问出错的地方是数据加载吗

用官网的例子修改的函数如下

def create_dataset(dataset_path, spilt, repeat_num=1, batch_size=32,num_classes=6):

    """

    Create a train or eval dataset.

    Args:

        dataset_path (str): The path of dataset.

        spilt (str): Whether dataset is used for train or eval.

        repeat_num (int): The repeat times of dataset. Default: 1.

        batch_size (int): The batch size of dataset. Default: 32.

    Returns:
