I'm trying to install VTK module for python, I am however unsuccesful in doing so. I have downloaded a VTK tar-file, but I'm unable to extract it. I'm capable of extracting other tar-files, so there must be something specific with this file I suppose.
This is my error:
gzip: stdin: invalid compressed data--format violated tar: Child returned status 1 tar: Error is not recoverable: exiting now
I hope somebody can help me with this.
The answer depends on the operating system you are using. This will be a lot easier if you can find a package or installer for your specific operating system and/or distribution.
If you are using Linux then look for the corresponding package in the distribution's package manager. For example, on Ubuntu Linux you should be able to install it using the following command:
sudo apt-get install python-vtk
If you are using Microsoft Windows, the easiest way would be to install Python(x,y). It comes with VTK support.
Additionally, Anaconda also includes VTK package as well as support for virtual environments. It might be a good option for some folks.
If you are using Mac OS X, try installing everything via MacPorts.
As @Nil mentioned in comments below, a standalone python interface to VTK is now provided by VTK developers. You may download it for Windows, Darwin, and Linux from here.
As mentioned by @Nil, VTK used to offer vtkpython binaries on their download page. However, they've dropped this since VTK-8.x.x as mentioned here:
Sorry, about that. We decided to drop the vtkpython binaries for 8. I want to focus our energies on supporting python wheel installs instead. There’s no timeline yet for a complete solution but we’ve made some good progress toward that recently here: https://github.com/jcfr/VTKPythonPackage.
Thus, the recommended way of installing vtkpython now is (see this page):
$ python -m pip install --upgrade pip
$ python -m pip install vtk
on Ubuntu, maybe this post will be helpful: http://kazenotaiyo.blogspot.jp/2010/06/installing-vtk-in-ubuntu-and-making.html
The first and easiest is to just install the packages with the Aptitude Package Manager:
sudo apt-get install libvtk5-dev python-vtk
If you want the newest version VTK, you can also build it yourself:
Make sure CMake is installed:
sudo apt-get install cmake
Download the VTK source from the Downloads page.
Untar it:
tar xvzf vtk-5.6.0.tar.gz
Create an Out-Of-Source build and configure with CMake:
mkdir VTK_BUILD
cd VTK_BUILD
ccmake ../VTK
Make sure you enable python wrapping and set your install prefix to where you want the package to go. The default /usr/local works fine.
sudo make -j 8 install
(the -j 8 for make just makes the build process parallel assuming you've got the processors for it)
You now have VTK installed. Congrats! if you try to run vtkpython though, you'll get an error:
vtkpython: error while loading shared libraries: libvtksys.so.5.6: cannot open shared object file: No such file or directory
To fix this, append these lines to your .bash_profile, .bashrc, or .profile file in your home directory:
# add vtk paths
LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/lib/vtk-5.6"
PYTHONPATH="$PYTHONPATH:/usr/local/lib/vtk-5.6"
You'll need to reset your terminal now.
That sets up your library and python paths for the vtkpython executable.
I have installed vtk without a problem under win7 via pip:
> pip install vtk
