NumPy is a library for the Python language, adding the support for large, multi-dimensional arrays and matrices, along with the large collection of high-level mathematical functions. If you have installed some of the high-level packages like scikit learn or TensorFlow, or using some software like Anaconda or Jupiter notebook, then the chances are that you have already installed because by installing that software, it will automatically be installed in our system.
Now, if you have not installed any software or packages in the past, then you don’t need them. You can use standalone install the packages and use it in your Python program.
