Selecting a machine learning library has an important impact on your application architecture. The key is to consider your project requirements. What kind of data do you have? What kind of problem are you trying to solve? Is your data big? Do you need distributed storage? What kind of algorithm are you planning to use? Once you figure out what you need to solve your problem, pick a library that best fits your needs.
In the next chapter, we will cover how to complete basic machine learning tasks such as classification, regression, and clustering by using some of the presented libraries.
