Install NumPy, SciPy, Scikit-learn under CentOS 6.5

First, update the Python version
1. View the Python version

[Email protected] ipython-5.1.0]# python-v

Python 2.6.6

2. Download python-2.7.3

https://www.python.org/download/releases/2.7.3/

python-2.7.3.tar.bz2

3. Unzip and change the working directory

TAR-JXVF python-2.7.3.tar.bz2

CD Python-2.7.3

4. Installation

./configure

Make all

Make install

Make clean

Make Distclean

/usr/local/bin/python2.7-v

5. Create a soft link to make the system default Python point to python2.7

[Email protected] python-2.7.3]# mv/usr/bin/python/usr/bin/python2.6.6

[Email protected] python-2.7.3]# ln-s/usr/local/bin/python2.7/usr/bin/python

[Email protected] python-2.7.3]# python-v

Python 2.7.3

6. Specify the python version of Yum

Fix system Python soft links point to Python2.7 version, since Yum is not compatible with Python 2.7, Yum does not work and we need to

Vi/usr/bin/yum Change the #!/usr/bin/python of the file header to #!/usr/bin/python2.6.6

Second, install Pip

1. Download and install Setuptools

2. Download and install Pip

Third, install NumPy, Pandas, SciPy, matplotlib

1. Installing dependent Packages

SciPy need to rely on third-party packages such as Atlas, Blas, etc.

Yum Install Blas-devel Lapack-devel

2. Install with PIP

Pip Install NumPy

Pip Install Pandas

Pip Install scipy

Pip Install Scikit-learn

Pip Install Matplotlib
