This can be a disadvantage for those who require fine-grained control over their neural network architectures.
• Limited support for graph-based models: Keras primarily focuses on sequential models and does not provide extensive support for graph-based models. While some graph-based architectures can be implemented in Keras, it may require workarounds and additional code to achieve the desired functionality.
• Performance overhead: As a high-level framework, Keras may introduce a performance overhead compared to lower-level frameworks like TensorFlow. This overhead can be noticeable in scenarios that require highly optimized and efficient computations.
• Documentation gaps: Although Keras has a large community and extensive documentation, there may still be some gaps or inconsistencies in the documentation. This can sometimes make it challenging for new users to find specific information or troubleshoot issues.
• Limited native support for non-standard layers: Keras provides a wide range of standard layers, but it may have limited native support for non-standard or custom layers. Users may need to implement their own custom layers or find alternative solutions to incorporate specialized layer types into their models.
• Compatibility issues with other frameworks: While Keras is designed to integrate seamlessly with TensorFlow, compatibility issues may arise when trying to combine it with other deep learning frameworks. This can be a limitation for users who prefer to work with multiple frameworks or want to leverage specific functionalities from other frameworks.

Cases when Keras does not work

1. Unsupported hardware: Keras relies on low-level libraries such as TensorFlow or Theano to perform computations. If you are working with hardware that is not supported by these libraries, Keras may not function properly. For example, if you have an outdated or unsupported GPU, you may encounter issues when running Keras code that requires GPU acceleration.
2. Version incompatibility: Keras is continually evolving, and updates are released regularly. If you have written code using an older version of Keras and try to run it with a newer version, it may result in compatibility issues. Certain functions or syntax may have changed, leading to errors or unexpected behavior.
3. Insufficient computational resources: Deep learning models, especially complex ones, require a significant amount of computational resources. If your hardware does not have enough memory or processing power to handle the model’s requirements, Keras may crash or run extremely slowly. This is particularly relevant when working with large datasets or models with a high number of parameters.
4. Data-related issues: Keras heavily relies on properly formatted and preprocessed data. If your input data is not properly prepared, Keras may not be able to process it correctly. This includes issues such as missing values, incompatible data types, or improperly scaled data. It is crucial to ensure that your data is in the correct format and matches the input requirements of your Keras model.
5. Improper model configuration: Keras provides a wide range of options for configuring and building models. If you make mistakes or provide incorrect configurations when defining your model, Keras may encounter errors during the compilation or training processes. It is important to carefully review and validate your model’s architecture, layer configurations, and input/output dimensions.
6. Software conflicts: If you have other software or libraries installed on your system that conflict with Keras or its dependencies, it can lead to issues. For example, incompatible versions of Python packages or conflicts between different deep learning frameworks can cause Keras to malfunction. It is essential to ensure that you have a clean and compatible software environment to avoid conflicts.
7. Programming errors: Keras, like any other programming framework, requires correct syntax and logical implementation. If you make programming errors such as typos, incorrect function calls, or incorrect data manipulation, Keras may not work as expected. It is crucial to carefully review your code for any potential mistakes.
8. Unsupported operations: Although Keras provides a wide range of functionalities, there may be certain operations or complex architectures that are not supported directly by Keras. In such cases, you may need to implement custom operations or consider using other deep learning frameworks that better suit your specific needs.
