Step by Step Procedure for configuring Deep Learning Packages in Python

By Prem Sankar C
Deep learning is getting popular with the data scientists. Here,  Im sharing my first-hand experience with the TensorFlow and Theano.  It was started to help the MTech Students from MG university. All Credits to goes to Noufal Salim who helped me to understand the configuration of different python deep learning environments.  Let us explore deep learning !!!


Before starting the installation guide, let us familiar with the technical terms and tools.
Anaconda is the leading open data science platform powered by Python

Keras is an open source neural network library written in Python

TensorFlow is an open source software library for machine learning  developed by Google 

Theano is a numerical computation library for Python 


Configuration Prerequisite: Python 2.7 , 64Bit
 

Step 1 : Download Anaconda 64 bit installer for Python 2.7 from continuum website  - Link

Step 2 :  Bash Anaconda - Goto corresponding download directory in Terminal  and In your terminal window type the below  instruction:

bash Anaconda2-4.3.1-Linux-x86_64.sh 
Iti will ask your permission for installing and preferred installation directory . It will create default environment . It will ask

" Do you wish the installer to prepend the Anaconda2 install location to PATH in your /home/prem/.bashrc ? [yes|no] "

>>> yes

Prepending PATH=/home/prem/anaconda2/bin to PATH in /home/prem/.bashrc
A backup will be made to: /home/prem/.bashrc-anaconda2.bak [default]

For this change to become active, you have to open a new terminal.

Step 3 : Add PATH

Add this line to the file .bashrc in your home directory:
 export PATH="/home/username/anaconda/bin:$PATH"

Type the following in new terminal


Step4:  >>conda update conda
Step5 : >>conda install Theano
Step6 : >>conda install tensorflow
Step7 : >>conda install keras


Step 8 : Activate the Anaconda Python by activating the corresponding path.

>>source activate PATH
In this , PATH is /home/prem/Anaconda2/

Step 9 :Run the program python filename.py

You can see lot of sample deep learning programs in Internet sites. Try it !!!

Future of Plastic Currencies in India

By iMobino
Financial Minister P Chidambaram had announced that the plastic copies of Rs.10 are going to come out soon. Reports indicate that the different countries in the world are also going to follow this path.  This decision is going to bring about a great change in the field of notes. The tradition of using paper for making notes by banks for about 300 years is going to be changed.  Only low value notes like 10Rs will come out first. Only later will the high amount notes will be issued. The opinion of the experts in the financial field is that no hurry is required for the issue of plastic notes. In the present situation of increasing fake note issues there is an opinion of using technology to trace notes that would be more advantageous.
