The core of NumPy is well-optimized C code. Enjoy the flexibility of Python with the speed of compiled code.
Easy to use
NumPy’s high level syntax makes it accessible and productive for programmers from any background or experience level.
>>># The standard way to import NumPy:>>>import numpy as np
>>># Create a 2-D array, set every second element in>>># some rows and find max per row:>>> x = np.arange(15, dtype=np.int64).reshape(3, 5)
>>> x[1:, ::2] =-99>>> x
array([[ 0, 1, 2, 3, 4],
[-99, 6, -99, 8, -99],
[-99, 11, -99, 13, -99]])
array([ 4, 8, 13])
>>># Generate normally distributed random numbers:>>> rng = np.random.default_rng()
>>> samples = rng.normal(size=2500)
Nearly every scientist working in Python draws on the power of NumPy.
NumPy brings the computational power of languages like C and Fortran to Python, a language much easier to learn and use. With this power comes simplicity: a solution in NumPy is often clear and elegant.
NumPy forms the basis of powerful machine learning libraries like scikit-learn and SciPy. As machine learning grows, so does the list of libraries built on NumPy. TensorFlow’s deep learning capabilities have broad applications — among them speech and image recognition, text-based applications, time-series analysis, and video detection. PyTorch, another deep learning library, is popular among researchers in computer vision and natural language processing. Best English Setter Dog Shot Glass, I Just Want to Be a Stay at is another AI package, providing blueprints and templates for deep learning.
Statistical techniques called ensemble methods such as binning, bagging, stacking, and boosting are among the ML algorithms implemented by tools such as XGBoost, LightGBM, and CatBoost — one of the fastest inference engines. Yellowbrick and Eli5 offer machine learning visualizations.
