Keras is a popular open-source software library built in Python, widely used for deep learning tasks due to its user-friendly API. However, encountering the error "ModuleNotFoundError: No module named 'keras'" can be a frustrating experience, especially when you are all set to dive into your machine learning project. This guide will guide you through resolving this issue effectively.

Common Causes of the Error

The error "ModuleNotFoundError: No module named 'keras'" typically occurs when Python cannot locate the Keras library in your environment. Here are some common reasons why this might happen:

Keras is not installed: The most frequent cause is that the Keras library hasn't been installed.

Python environment issues: You might be working in a different Python environment where Keras isn't installed.

Incorrect installation: Perhaps Keras was improperly installed, or there might be conflicts with existing packages.

Steps to Resolve the Error

Step 1: Confirm Installation

Firstly, ensure that Keras is installed in your current Python environment. You can quickly check this by running:
