13. Bob

Bob is a free signal-processing and machine learning toolbox which is used for image and video processing  developed at Idiap Research Institute in Switzerland. The toolkit is written in a mix of C++ and Python and is outlined to reduce development time more efficiently. 

14. PyBrain

Pybrain is an open-source Machine learning Library of Python which holds algorithms for neural networks .It has many predefined conditions to test and compare algorithms. The library provides  simple training algorithms for networks, datasets, and trainers to test and train the network. 

15. Theano

Theano helps us to define, optimize and evaluate mathematical expressions which includes multi-dimensional arrays effectively. It is mainly used in developing Deep Learning Projects. For handling large volumes of data, coding through C becomes slower.  Theano works much faster specially on the Graphics Processing Unit (GPU) rather than on CPU.  Another advantage of Theoano is that it can identify unstable expressions and calculate stable algorithms. 

16. SymPy

SymPy library is used for arbitrary floating point arithmetic and symbolic mathematics which is a powerful assistance for Computer Algebra System (CAS). One can keep the code as simple as possible.  SimPy is set down in Python only and can be implanted in other applications and extended with custom functions. 

17. MILK

Milk is a machine learning library in Python which is mainly used for supervised classification with a range of other classifiers such as random forests, SVMs, decision trees and k-NN. MILK provides support to k-means clustering and affinity propagation for unsupervised learning. Milk is flexible regarding its inputs. It is developed for numpy arrays, but can often handle anything. 

18. Caffe2

Caffe2 is a Modular and Scalable Deep Learning Framework which is an easy and uncomplicated method to experiment with deep learning which facilitates quick prototyping of ideas and experiments. 

19. NLTK

NLTK is a Python NLP library which provides processing solutions for categorizing text, numerical and symbolic language processing and analyzing linguistic structure etc. 

20. Seaborn

Seaborn is a Python data visualization library built on matplotlib and integrated with Pandas data structure. It enables a high-level interface for drawing attractive and informative statistical graphics and models like heat maps. 

21. Dash
