Python is the main programming language used in the development of machine learning models. It is a high-level programming language, preferred by AI practitioners for its intuitive syntax and wide community support, among other things.
Check out a Python tutorial which uses Google Colab, an interactive computing platform, where you can execute Python code directly in a browser. Google Colab supports simple code like the one presented in the tutorial, as well as much more complex code for building and training machine learning models.
PyTorch is a widely used machine learning framework, based on Python. It provides high-level functionalities like building a machine learning model from pre-configured blocks, loading data from files of various formats, executing model training with just a few lines, and many more.
Notice that at the top of every tutorial page, there is a “Run in Google Colab” link that opens up the tutorial in Google Colab and allows you to interact with the code.
