Скачать или смотреть Setting Up Your Scikit-learn Environment

Before we dive into PCA, let's make sure your Scikit-learn environment is set up correctly. First, you need to have Python installed on your machine. If you haven't yet, visit python.org and download the latest version. Next, you'll need to install Scikit-learn using pip, which is as simple as running 'pip install scikit-learn' in your command line or terminal. Additionally, I recommend using a Jupyter Notebook for this tutorial as it allows for interactive data analysis and visualization. Ensure you have other necessary packages like NumPy and Matplotlib installed, which can be done through pip as well. Remember that compatibility is key, so make sure all your packages are up to date and compatible with each other.
