无法找到 Checkpoint 文件

当尝试指向 checkpoint/ 目录中的任何文件时，我得到以下错误： `Traceback (most recent call last): File "evaluate.py", line 212, in <module> main() File "evaluate.py", line 209, in main batch_size=opts.batch_size) File "evaluate.py", line 102, in ffwd saver.restore(sess, checkpoint_dir) File "/root/anaconda3/envs/tf-gpu/lib/python3.7/site-packages/tensorflow_core/Python/training/saver.py", line 1290, in restore {self.saver_def.filename_tensor_name: save_path} File "/root/anaconda3/envs/tf-gpu/lib/python3.7/site-packages/tensorflow_core/Python/client/session.py", line 960, in run run_metadata_ptr) File "/root/anaconda3/envs/tf-gpu/lib/python3.7/site-packages/tensorflow_core/Python/client/session.py", line 1183, in _run feed_dict_tensor, options, run_metadata) File "/root/anaconda3/envs/tf-gpu/lib/python3.7/site-packages/tensorflow_core/Python/client/session.py", line 1361, in _do_run run_metadata) File "/root/anaconda3/envs/tf-gpu/lib/python3.7/site-packages/tensorflow_core/Python/client/session.py", line 1386, in _do_call raise type(e)(node_def, op, message) tensorflow.Python.framework.errors_impl.DataLossError: 无法打开表文件 checkpoint_dir/checkpoint: 数据丢失: 不是 sstable (错误魔术数字): 可能您的文件使用了不同的文件格式，需要使用不同的恢复运算符?`
