ModuleNotFoundError: 'keras' not found - How to fix

The error message 'ModuleNotFoundError: No module named 'keras'' indicates that the 'keras' library is not installed on your system or in the Python environment you're using.

To fix this, you can install 'keras' by running 'pip install keras' in your Jupyter notebook or terminal/command prompt. If you're using a virtual environment, make sure to activate it before installing.

Alternatively, consider using other popular deep learning libraries like 'tensorflow' or 'pytorch' instead of 'keras'. These libraries offer similar functionality and are also widely used in the field.
