Hello, i use tensorflow-gpu==2.4.1, keras==2.2.4 ,but have the following error in load_model:

you can following this steps, it might be tf version problem

thank you , I fix this error , but have the next error:

python version error. because your checkpoint is trained based on python3.5, so you should change python version to 3.5 intead of 3.6
