ARCS supports Anaconda Python for both Python 2.x and Python 3.x. The default Anaconda installation comes with most of the modules researches and students need to accomplish their tasks. If additional modules are needed send an email to arcs@njit.edu . If Anacaconda supports the module ARCS will install the module for you. In the event that Anaconda does not have the module available or you prefer to maintain your own python anvironment there are two methods you can use. You do NOT need root permissions to do this.

Install the module in your home directory

The following is an example of installing the "stemming" module in the user home directory without root privileges using "pip":

kong-43 ~ >: pip install --user stemming

Python 2.7.11 |Anaconda 4.0.0 (64-bit)| (default, Dec  6 2015, 18:08:32)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-1)] on linux2
Type "help", "copyright", "credits" or "license" for more information.

>>> import stemming
>>>

The --user switch tells the pip command to install the module in ~/.local/lib/pythonX.Y/site-packages. The directory will be created if it doesn't exist.

Virtualenv

Virtualenv allows a user to maintain a virtual python environment where the user can install packages as needed.

This example uses the installed Intel Python3

band ~ >cd pythonapps
band pythonapps >: virtualenv testenv
