Have you encountered the error message “TypeError: init() got an unexpected keyword argument ‘ragged'” while trying to run a trained Keras model? Don’t worry; you’re not alone! This error often occurs when there is a mismatch between the versions of Keras and TensorFlow being used. In this article, we will explore the cause of this error and provide a solution to help you overcome it. So, let’s dive in!
Understanding the ‘Unexpected keyword argument ‘ragged” Error
The error message “TypeError: init() got an unexpected keyword argument ‘ragged'” indicates that the ‘ragged’ keyword argument is being passed to the model’s constructor (init()), but it is not recognized or supported in the current context. This error typically arises when there is a version mismatch between Keras and TensorFlow.
Solution: Importing TensorFlow’s Keras API
To resolve the issue, we need to ensure that we are using the correct API for loading the model. In your code, you are importing Keras directly, but since the model was saved with TensorFlow’s Keras high-level API, we need to make a small modification.
- Update your import statements as follows:pythonCopy code
from tensorflow.keras.preprocessing.image import img_to_array from tensorflow.keras.models import load_model - Modify the loading of the model to use TensorFlow’s Keras API:pythonCopy code
model = load_model(MODEL_PATH, compile=False)
By making these changes, you are now using TensorFlow’s Keras API to load the model. This ensures compatibility between the saved model and the version of TensorFlow being used.
Additional Considerations
- Ensure that you have the correct path to your model file (MODEL_PATH) and that it points to the correct location.
- Verify that you have the required versions of Keras and TensorFlow installed. In your case, you mentioned using Keras v2.3.1 and TensorFlow v1.13.1. While these versions should work together, it’s always a good practice to check for any compatibility issues and consider upgrading to the latest versions.
Conclusion
The “TypeError: init() got an unexpected keyword argument ‘ragged'” error can be resolved by using TensorFlow’s Keras API instead of importing Keras directly. By making this change and ensuring version compatibility, you will be able to load your trained Keras model successfully.
Remember, keeping your libraries and dependencies up to date is crucial for ensuring smooth compatibility and avoiding unexpected errors.
