installing Mayavi with pip - no module named vtk

StackOverflow https://stackoverflow.com/questions/12182052

Frage

I want to use Mayavi.

Situation

  • I use a MacBook Air, with OSX 10.7.3.
  • I use Python 2.7.2
  • I have virtualenv installed. But I have not used it for this installation.

I've manually installed all it's dependencies, including VTK.

For VTK, I followed its installation guide and installed the python wrapper.

Now if I open a new terminal window and open python, I can import vtk without any error.

Problem

I try to install Mayavi with the following command:

pip install mayavi

But the following error occurs:

I think the problem is with vtk.

Can anyone help me?

Other Details

Running sudo pip install mayavi does not solve the problem.

Lösung

Your pip is probably using a different python, kind of you have vtk installed using /usr/local/bin/python, while your pip binary uses /usr/bin/python.

Check it:

$ head -n1 $(which pip)

In order to get it solved, you can choose to use a virtualenv, or install pip using /usr/local/bin/python:

curl https://raw.github.com/pypa/pip/master/contrib/get-pip.py | /usr/local/bin/python

Andere Tipps

I'm on Debian but this should work for you as well

I was stuck with installing vtk into a virtualenv, after hours of search with no results I did the following and it worked.

  1. install python-vtk from repositories systemwide

  2. copy vtk folder from /usr/lib/pymodules/python2.7 to /PATH/TO/YOUR/VIRTUALENV/lib/python2.7/site-packages

In your case the system-wide python packages folder would probably be different but you can easily find it by firing up system python and entering the following:

import vtk,sys
print(sys.modules['vtk'])

After this trick mayavi was succesfully installed into my virtualenv using pip install mayavi and pip install envisage.

Edit: instead of copying it might better to just symlink the folder in step 2

I had the same problem and the first answer didn't help me because pip was in the right directory, but it turned out I didn't have vtk installed - running sudo apt-get install python-vtk fixed the issue and I was able to successfully run pip install mayavi after that.

I had the same problem when installing mayavi with python installed in pyenv, and I solved this problem by copy directory to /home/myname/.pyenv/versions/2.7.12/lib/python2.7/site-packages, below is my method:

  1. install vtk and python-vtk

    sudo apt-get install vtk6
sudo apt-get install python-vtk

  2. try python -c "import vtk", if failed again, go to step 3

  3. the import error may caused by the loss of vtk package folder in your current python, so we should find the vtk folder and copy to your current python(most possible the python in pyenv shims directory)'s directory .

    the path of the vtk folder in my ubuntu is

    /usr/lib/python2.7/dist-packages/vtk

    just copy the vtk folder to your current python's /site-packages, e.g. 

    cp -r /usr/lib/python2.7/dist-packages/vtk /home/myname/pyenv/versions/2.7.12/lib/python2.7/site-packages

  4. try python -c "import vtk" again.

  5. if no import error, just do

    pip install mayavi

I insisted in sudo install for several times, finally got solved, don't know how to explain.

sudo python2 -m pip install mayavi

sudo python3 -m pip install mayavi

UPDATE

I can't install via pip for laptop. Then I install the latest mayavi by

git clone https://github.com/enthought/mayavi.git
cd mayavi
pip install -r requirements.txt
pip install PyQt5  # replace this with any supported toolkit
python setup.py install  # or develop

after installation. Test with

mayavi2

Then report say couldn't find module PyQt5.Qtsvg, so

sudo apt install python3-pyqt5.qtsvg

Now it works.

I installed vtk using Homebrew:

$ brew install vtk

hope this helps.
