You can install on Ubuntu for CPU sudo apt install caffe-cpu and for GPU sudo apt install caffe-cuda


PyTorch is another open-source machine learning framework. It includes TorchScript, a compiler that converts PyTorch models into a statically typed graph. Data scientists can then carry out optimizations and adjustments in eager mode and thereby incrementally convert their models to TorchScript. It can be used to implement network architectures like RNN, CNN, LSTM, etc and other high-level algorithms.


PyTorch has known the Open Neural Network eXchange (ONNX) format for exporting trained or untrained models to a standardized format for some time. ONNX enables the exchange between different frameworks and, for example, simplifies the transfer of models from PyTorch to TensorFlow and vice versa.

In addition, the connection to TensorBoard it includes Python-based libraries based on Toch such as torchaudio, torchtext, torchvision and more.

Spark MLlib

Apache Spark is a fast and general-purpose computing engine designed for large-scale data processing. Spark is a Hadoop MapReduce-like general-purpose parallel framework open-sourced by UC Berkeley AMP lab (UC Berkeley’s AMP Lab). Spark has the advantages of Hadoop MapReduce; but unlike MapReduce, the intermediate output of the job can be stored in memory, so it is no longer necessary to read and write HDFS, thus Spark can be more suitable for data mining and machine learning algorithms that need iterative MapReduce algorithms.

Spark MLib Apache Machine learnign

MLlib (Machine Learning lib) is Spark’s implementation library for commonly used machine learning algorithms. It also includes related tests and data generators. MLlib currently supports 4 common machine learning problems: classification, regression, clustering, and collaborative filtering.

Theano is based on Python and is a library that is good at processing multi-dimensional arrays (similar to NumPy in this respect). It was designed to perform the operations of large-scale neural network algorithms in deep learning. Theano’s early developers were Yoshua Bengio and Ian Goodfellow. Due to their academic background, it was originally designed for academic research. When combined with other deep learning libraries, it will be very suitable for data exploration.

Theano deep learning

Theano can be better understood as a compiler for mathematical expressions: define your desired result in a symbolic language, and the framework will compile your program to run efficiently on the GPU or CPU.

For a long time in the past, Theano has been the industry standard for deep learning development and research. Compared to a deep learning library, it is more like a research platform. You need to do a lot of work from the bottom to create the models you need, which means that it is very flexible.

No matter how good the tools are, they have withdrawn from the stage of history. Theano, which once won the favour of the academic community, is no exception.

However, the key developers of this deep learning framework have stopped their contribution in 2017, yet its community is still actively supporting the project which can be seen clearly on the Github.
