How can I get the Nibabel module for Python 3? Only the Nibabel module for Python 2 is in the repository.


For Ubuntu 14.04 and earlier, this is not in the repositories, but you can install is yourself. (I tested this on Ubuntu 12.04 and 14.04).

A prerequisite is NumPy. If you don't have this for Python3, then open a terminal (CTLALTT).

sudo apt-get install python3-numpy

Easy Way (using PIP)

If you don't have PIP for Python 3, you can get it on Ubuntu 14.04 by doing

sudo apt-get install python3-pip

and on Ubuntu 12.04, by doing

sudo apt-get install python3-setuptools
sudo easy_install3 pip

Now, to install Nibabel, do

sudo pip3 install nibabel


Hard Way (build from source)

We'll use git to download Nibabel, so type this command

sudo apt-get install git

Download nibabel by typing

git clone https://github.com/nipy/nibabel.git

then move to the new nibabel directory by doing

cd nibabel

At this point, you can do sudo python3 setup.py install, but it's better to use the program checkinstall which will make it easier to uninstall the package if you need to. So type

sudo apt-get install checkinstall

and install nibabel with

sudo checkinstall python3 setup.py install

If it asks Should I create a default set of package docs? [y]:, hit YENTER.

When it says Please write a description for the package, you can type whatever (I typed "python3-nibabel") and hit ENTERENTER .

When it says This package will be built according to these values:, hit ENTER.

If it asks Do you want me to list them? [n]:, hit NENTER.

If it asks Should I exclude them from the package? ..., hit YENTER.

You should be done. Type python3, then import nibabel to check that it worked. If you need to uninstall it, open a terminal and type: sudo apt-get remove nibabel.
