## Best Python libraries for Machine LearningMachine learning is a science of programming the computer by which they can learn from different types of data. According to machine learning's definition of In previous days, the users used to perform tasks of machine learning by manually coding all the algorithms and using mathematical and statistical formulas. This process was time-consuming, inefficient, and tiresome compared to Python libraries, frameworks, and modules. But in today's world, users can use the Python language, which is the most popular and productive language for machine learning. Python has replaced many languages as it is a vast collection of libraries, and it makes work easier and simpler. In this tutorial, we will discuss the best libraries of Python used for Machine Learning: - NumPy
- SciPy
- Scikit-learn
- Theano
- TensorFlow
- Keras
