Matlab version is also in the fold.

Requirements for Run: We need python 3(2 also work) and tensorflow > 1.4

1). Install using the Homebrew package manager:

mac:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" export PATH="/usr/local/bin:/usr/local/sbin:$PATH" brew update brew install python@2 # Python 2 sudo pip install -U virtualenv # system-wide install

Ubuntu:

sudo apt update sudo apt install python-dev python-pip sudo pip install -U virtualenv # system-wide install

2). Create a new virtual environment by choosing a Python interpreter

virtualenv --system-site-packages -p python3.6 ./venv source ./venv/bin/activate pip install --upgrade pip

3). install tensorflow refer to https://www.tensorflow.org/install/

4). install packages pip install networkx

    pip install scipy 
    
    pip install matplotlib 
    
    pip install numpy 
    
    pip install tqdm 
    
    pip sklearn
