However, as time passes most people switch over to the NumPy matrix. If you don’t have Python yet and want the simplest way to get started, we recommend you use the Anaconda Distribution - it includes Python, NumPy, and many other commonly used packages for scientific computing and data science. Anyways I will give you an generic solution. I guess if you just remove .to_numpy() it will work on earlier version. NumPy (Numerical Python) is an open-source library for the Python programming language. Then all the other modules I need specific to the environment can be installed with pip as usual.
