Hi Nishant, Thanks for your question. First, on Windows, I strongly recommend you install [Anaconda](https://www.anaconda.com/distribution/), Python 3.7 version. TensorFlow does not work with Python 3.8 yet, and installation is much...

Hi @Nishant90ML , As @GoldenRaven answered, the error message says that the variable `housing_prepared` is not defined. This probably means that you did not run the cell that defines it,...
