About

TensorFlow is an oss library for numerical computation using data flow graphs. Nodes in the graph represetn mathematical operations, while the graph edges represnt the multimensional data arrays(tensors) communicated between them. The flexible architecture allows you to deploy computation to one or more CPUs or GPUs in a desktop, server, or moblie device with a single API. TensorFlow was originally developed by researchers and engineers working on the Google Brain Team within Google's Machine Intelignece research organization for the purposes of conducting machine learning and deep neural networks research, but the system is general enough to be applicable in a wide variety of other domains as well.

Installing build-essentials CentOS

Installing build tools in CentOS

Since I prefer CentOS as my server platform,I also occasionally need to install package using yum

To install the common build tools using yum in CentOS you'll want to install the group package "Development Tools", which is similar to build-essentials in Debian/Ubuntu flavors of linux. You'll probably also want to install kernel-devel and kernel-headers if they're not already installed:

centOS> yum groupinstall "Development Tools" centSO> yum install kernel-devel kernel-headers

This should give you a copy of make, gcc, gdb, and all those other tools you ware looking for.

Download Python Sourcecode

centOS> wget https://www.python.org/ftp/python/${VER}/Python-${VER}.tgz

Build Python

centOS> tar xzvf Python-${VER}.tgz centOS> cd ./Python-${VER} centOS> ./configure --with-threads centOS> make install
