I installed a virtual environment for python. I succeeded to install numpy and scipy but not parallel python. How can I install or build third modules into the virtualenv?

I tried to sudo apt-get python-pp , it worked and installed the last version but I can't call the module import pp after launching the virtualenv

Previously done to install python + last scipy stack in a terminal:

sudo apt-get install build-essential gfortran libblas3gf libblas-doc libblas-dev liblapack3gf liblapack-doc liblapack-dev

sudo apt-get install python-dev

sudo apt-get install python-pp

sudo apt-get install python-virtualenv

mkdir + cd into appropriate dedicated folder

virtualenv --no-site-packages virtualenv

source ./virtualenv/bin/activate

pip install numpy scipy

How to install and build python third modules into the virtualenv? Thanks for your incoming help and explanations.

Answer: after pip install numpy scipy , go into ./virtualenv/bin/ and there apply Nicholas commands:

wget http://www.parallelpython.com/downloads/pp/pp-1.6.4.zip
unzip -e pp-1.6.4.zip
cd pp-1.6.4
python setup.py install

to test,

import pp

Thanks to Nicholas I

  • this question should also help people/students/scientifics that need to install latest version of scipy stack and python ^^

    Could you expand on your answer and state what these commands achieve? Mar 19, 2015 at 12:33
  • Ok, it works. To complete your answer, I installed pp from virtualenv. I suppose that such install forces the process to happen into the virtualenv … or may be it's a known issue from apt-get install python-pp? I agree with M.Lindman, you are quite sparse in "explanations" ^^ Thanks anyway!
