 You have to state above commands in your script when you run python on batch jobs. 
 
-== Installing Packages ==
-One of the best things about Python is the number of packages provided by the user community. On a personal machine, the most popular method today for managing these packages is the use of a package manager, like pip. Unfortunately, these require root access and are not a viable solution on Cypress. 
 
-There is an easy solution. Any well written Python package will allow the user to perform a "user only installation." This typically only requires the addition of a single flag when installing the package.
-
-As an example, let's install the package Parallel Python (pp). If you wish to follow along, the package can be downloaded [http://www.parallelpython.com/content/view/18/32/ here].
-
-When you have the packages tar file in the desired directory, you can unpack it with the '''tar''' command
-
-{{{
-[tulaneID@cypress1 ~]$ tar -xvf pp-1.6.4.tar.gz

-Our installation failed because we lack the permissions to add files to the system wide Python installation. But that's not what we want anyway, we just want to install the package for our personal use. We need to add the flag '''- -prefix=$HOME''' to tell the installer where to place the package.
