yum install python27

---- install numpy
yum install python27-pip python27-devel parallel
cd /usr/bin
ln -s pip2.7 pip
pip install --upgrade pip
pip install requests solrpy
yum install gcc

---- numpy, scipy on ubuntu
yum install python-pip python-dev build-essential
yum install libatlas-base-dev gfortran
pip install numpy scipy

yum install lapack-devel
pip install scipy

---- Install pip

yum install python-pip
if you have an error like: "urllib3/util/ssl_.py:90: InsecurePlatformWarning" do:

sudo yum remove python-openssl

---- look for a package:
pip search requests |grep requests
---- see if it is installed
pip show requests
---- see all installed
pip freeze

---- MySQL
pip install MySQL-python       didn't work right away. I had to do this

yum search all MySQL
yum install MySQL-client
yum install MySQL-devel
yum install MySQL-python27

---- image hash
pip install ImageHash

--- look for local Python package
pip list | grep cv

--- my-virtualenv

       < Python 3.3:    virtualenv my-virtualenv -p /usr/bin/python

       else                    /usr/bin/python3 -m venv my-virtualenv

  my-virtualenv$ source bin/activate

  (my-virtualenv) lee@mycomp:~/python/flask/my-virtualenv$ deactivate
