Often you may encounter, ModuleNotFoundError: No module named ‘tensorflow’, error when you are trying to run a Python script that uses TensorFlow for a Machine learning and deep learning projects. This means Python can’t find the TensorFlow library in your current environment. Which usually happens when:

TensorFlow is not installed in the environment being used (i.e., virtual environment)
You're using the wrong Python environment (and so TensorFlow may be installed elsewhere)
There's a typo in the module name
Incorrect system PATH configuration, preventing Python from detecting installed packages

Follow the steps below to fix the Issue:

1. Install TensorFlow
