[ITK] [ITK-users] SimpleITK Anaconda Issue

[Yaniv, Ziv Rafael (NIH/NLM/LHC) [C]]

Hi Tassilo,

Did you downgrade to libpng1.5 after creating the virtual environment? This is what I suggested in the thread you cited and was the solution at the time.  It no longer works because anaconda upgraded additional packages.

When you create the virtual environment with libpng set to 1.5 (conda create -n sitkpy anaconda libpng=1.5) all of the dependent packages are downgraded to work with this version of libpng and then you will not have this issue. The three steps are given in the FAQ that I pointed you to - I am assuming here you did not follow that solution, it is pasted below for your convenience:

conda create -n sitkpy anaconda libpng=1.5
conda install -c https://conda.binstar.org/simpleitk/channel/main SimpleITK
conda install libpng=1.5

If you followed this set of instructions and it doesn't work, let us know and we will try to recreate the problem and find a solution.

          regards
              Ziv

Hello Tassilo,

Please follow the instructions found in our FAQ 'I am using the binary distribution of SimpleITK for Anaconda, why do I get an error about libpng?' found here: http://www.itk.org/Wiki/SimpleITK/FAQ

We are working on a more permanent solution for our next release.

               regards
                      Ziv

Hi,

I have issues getting my SimpleITK running on a Linux machine.

I used to get errors:

http://public.kitware.com/pipermail/community/2015-May/009117.html


ImportError: libpng15.so.15: cannot open shared object file: No such


Then I took an earlier version of libpng as mentioned here:

http://public.kitware.com/pipermail/community/2015-May/009120.html

conda install libpng=1.5.13


But then I get the following error:


/home/tjklein/anaconda/lib/python2.7/site-packages/matplotlib/colorbar.py in <module>()
     32 import matplotlib.artist as martist
     33 import matplotlib.cbook as cbook

     21 from matplotlib.ft2font import LOAD_TARGET_LIGHT

     56 import matplotlib
     57 from matplotlib import afm

     59 from matplotlib import rcParams, get_cachedir
     60 from matplotlib.cbook import is_string_like

ImportError: libpng16.so.16: cannot open shared object file: No such file or directory


Any idea?

Best,
 Tassilo
