ModelCheckpoint callback crashes if filename doesn't end with .weights.h5

[erickrf]

When using the callback ModelCheckpoint, the path argument for saving the model must end with .weights.h5, or else it raises an error like this:

ValueError: The filename must end in `.weights.h5`. Received: filepath=/tmp/model.keras

Hi,

Thanks for reporting the issue.

Below is the recommended way of saving model weights in new Keras 3.

model.save('my_model.keras') # (recommended)```


to save the weight file using .h5, save it like below.


`model.save_weight('my_model.weights.h5`)`
