Can not install VTK with Anaconda

Question

I can not install VTK by anaconda in Mac OS X. I use

conda install -c anaconda vtk=6.3.0

Python 2.7 but get the following error:

UnsatisfiableError: The following specifications were found to be in conflict: - python 3.6* - vtk 6.3.0* -> python 2.7* -> openssl 1.0.1* Use "conda info " to see the dependencies for each package.

But I've updated Python to 3.6, and the same error.

Answer 2

I would suggest installing directly from the wheel file. You can get the VTK wheel file from here ( wheel file directory site ). This site has pretty much every wheel file so it is your friend! just search for it and you will see a bunch of .whl VTK files.

just download the wheel file that matches your anaconda python root version (either 3.5, 3.6, 2.7 etc.) and either 32 or 64 bit (depending on your python version).

To install from a wheel file, open a terminal in the directory the wheel is in and type

pip install "your_wheel_file_name"

If you want to install it for a conda environment, just activate the environment first ( activate "env_name" ) and then install from the wheel file.

Try this out for me:

conda create --name vtk_test python=2.7 vtk

This will create a new environment with VTK, Python and their dependencies inside.
