  • 0

I have downloaded numpy and matploblib tar.gz files. Now I want to install them on RedHat 5.

I don’t have root privileges. I have read INSTALL documents but I didn’t understand how to install these.

  1. Can I install these libraries without root privileges?
  2. If yes, how do I install them? Could you give me exact commands?
  3. Don’t these libraries consist of python modules? So all I have to do is copy those modules to PYTHONPATH, right?

    1. Yes, just use the --user flag when installing the package (provided you have a recent enough version of Python)

      More info on the --user flag is available in the documentation. Usually, a ~/.local directory will be created (if necessary), your packages should be present in ~/.local/lib/python$VERSION/site-packages.

    2. Install NumPy before matplotlib. To do that, just enter 

      python setup.py install --user

      in the directory where you unzipped the archive. Repeat for matplotlib.

      Don’t forget to read the installation instructions for NumPy (and for matplotlib too, of course). Should you have a problem, it’ll likely be covered in the documentation.

    3. Once you’re done with the installation, just update your $PYTHONPATH with a link to ~/.local/lib/python$VERSION/site-packages

    If you have an old version of Python that doesn’t recognize the --user flag, you should still be able to give the path of the installation with the --prefix flag. You could use --prefix=~/.local in order to match what would have happened if you had a more recent version of Python
    (Note that this topic is covered in the NumPy installation guide…).
