How to apply checkpoints which trained on Keras2？

[forestbat]

I want to use your pretrained checkpoint model on my project, however it crashed under Keras3:

model = deepwatermap.model()
model.load_weights(checkpoint_path)

ValueError: File format not supported: filepath=C:\Users\Administrator\deepwatermap-checkpoints. Keras 3 only supports V3 `.keras` and `.weights.h5` files, or legacy V1/V2 `.h5` files.

And when use another method to read your ckpt file, it crashed like that:

import  from tensorflow.python.training.py_checkpoint_reader import NewCheckpointReader
reader = NewCheckpointReader(r'C:\Users\Administrator\deepwatermap-checkpoints')

; Input/output error
Traceback (most recent call last):
  File "C:\Users\Administrator\AppData\Roaming\JetBrains\IntelliJIdea2023.3\plugins\python\helpers\pydev\pydevconsole.py", line 364, in runcode
    coro = func()
           ^^^^^^

           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xbe in position 177: invalid start byte

So do you have time to retrain a model or tell me how to solve this problem?
