Python Tensorflow.restore中输入的格式

我使用的模型中的一个参数是以下文件，该文件以名称checkpoint（无扩展名）传递：

模型检查点路径：“epoch-29”

所有模型检查点路径：“epoch-29”

它用于以下代码段中：

parser = argparse.ArgumentParser()     
parser.add_argument('--checkpoint', help='path to checkpoint to restore',default='epoch')


args = parser.parse_args()
    

# load config
config = generate_config()

# build model and restore from checkpoint
model = build_model(num_output_neurons=config.n_output_neurons, y_input=config.n_mels, num_units=config.n_dense_units, num_filts=config.n_filters)

checkpoint = tf.train.Checkpoint(model=model)
checkpoint.restore(args.checkpoint)

我得到以下错误：

tensorflow.python.framework.errors_impl.DataLossError: Unable to open table file ...: Data loss: not an sstable (bad magic number): perhaps your file is in a different file format and you need to use a different restore operator?

方法还原的正确格式是什么？
