Installing vtk in python

The VTK package has recently been made available for pip, but when I try to run pip install --user --upgrade vtk (or with pip3) on Ubuntu 14.04, all I get is:

Could not find any downloads that satisfy the requirement vtk in /usr/lib/pymodules/python2.7
Downloading/unpacking vtk
Cleaning up...
No distributions at all found for vtk in /usr/lib/pymodules/python2.7
Storing debug log for failure in /home/ignacio/.pip/pip.log

and the log file shows:

Getting page https://pypi.python.org/simple/vtk/
URLs to search for versions for vtk in /usr/lib/pymodules/python2.7:
* https://pypi.python.org/simple/vtk/
Analyzing links from page https://pypi.python.org/simple/vtk/

  ...

But I surely have CPython 2.7.6 and 3.4.3 (or that's what they say), and I've installed other packages with pip/pip3. What could be the reasons it "is not compatible with this Python"?

The output of python -c "from pip import pep425tags;print(pep425tags.supported_tags)" includes ('cp27', 'cp27mu', 'manylinux1_x86_64')

I had seen the solution suggested for this kind of issues:

$ pip install --update pip

And I had updated pip before, of course. It turns out that the new pip version was not being used, probably because I had installed it for the user, not for the system.

So at the end it worked by using python -m pip instead of just pip:

$ python -m pip install --upgrade --user vtk

And then:

$ python -c 'import vtk ; print vtk.vtkVersion.GetVTKVersion()'
8.1.0
