Fixing AttributeError: 'Sequential' Object Has No Attribute 'model/load_model/save_model' in Python

If you've been working with the Keras library in Python, you might have encountered the error: AttributeError: 'Sequential' object has no attribute 'model'. This can be quite a frustrating issue, especially for beginners. Along with this, similar errors such as AttributeError: 'Sequential' object has no attribute 'load_model' and AttributeError: 'Sequential' object has no attribute 'save_model' may occur.

Understanding the Sequential Object

Keras' Sequential class is a simple, linear stack of layers. You simply add one layer at a time, from input to output. Here is a basic example:

After defining your model, you might think of saving, loading, or accessing the underlying model. This is where some common pitfalls occur.

The AttributeError: 'Sequential' Object Has No Attribute 'model' Error

When encountering AttributeError: 'Sequential' object has no attribute 'model', it likely means you're trying to access an attribute named model which doesn't exist in the Sequential class.

Solution

Simply access the Sequential object directly, without trying to reach into it for a model attribute:

The AttributeError: 'Sequential' Object Has No Attribute 'load_model' Error

You might also encounter AttributeError: 'Sequential' object has no attribute 'load_model' when trying to load a saved model directly using a Sequential object.

The AttributeError: 'Sequential' Object Has No Attribute 'save_model' Error

Similarly, AttributeError: 'Sequential' object has no attribute 'save_model' might arise when trying to save a model.

Solution

The Sequential class has a save method for saving models:

Conclusion

Understanding how to handle AttributeError issues when working with Keras can save you a lot of time and frustration. Always check the available methods and attributes of the class you're working with by referring to its documentation or using Python's built-in dir() function to inspect the object.

By adhering to these guidelines, you'll be less likely to encounter these common attribute errors and more likely to develop smoother, error-free code.

Happy coding!
