#38530: py27-matplotlib @1.2.0 +python import error ------------------------+-------------------------------- Reporter: CK171080@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.1.3 Keywords: | Port: ------------------------+-------------------------------- I am using MacPorts on OS X 10.8 (Mountain Lion) and XCode 4.6.1. I am encountering problems with matplotlib and I have not found any solution browsing existing bug reports and the internet. Maybe there is someone around who can help... I installed py27-matplotlib without any compilation error. However when trying to import matplotlib.pyplot in ipython (also installed via macports) I get the following error: {{{ In [1]: import matplotlib.pyplot as plt --------------------------------------------------------------------------- ImportError Traceback (most recent call last) <ipython-input-1-eff513f636fd> in <module>() ----> 1 import matplotlib.pyplot as plt /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7 /site-packages/matplotlib/pyplot.py in <module>() 95 96 from matplotlib.backends import pylab_setup ---> 97 _backend_mod, new_figure_manager, draw_if_interactive, _show = pylab_setup() 98 99 @docstring.copy_dedent(Artist.findobj) /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7 /site-packages/matplotlib/backends/__init__.pyc in pylab_setup() 23 backend_name = 'matplotlib.backends.%s'%backend_name.lower() 24 backend_mod = __import__(backend_name, ---> 25 globals(),locals(),[backend_name]) 26 27 # Things we pull in from all backends /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7 /site-packages/matplotlib/backends/backend_macosx.py in <module>() 19 20 import matplotlib ---> 21 from matplotlib.backends import _macosx 22 23 ImportError: dlopen(/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7 /site-packages/matplotlib/backends/_macosx.so, 2): Symbol not found: __cg_jpeg_resync_to_restart Referenced from: /System/Library/Frameworks/ImageIO.framework/Versions/A/ImageIO Expected in: /opt/local/lib/libjpeg.9.dylib in /System/Library/Frameworks/ImageIO.framework/Versions/A/ImageIO }}} I get the same error using the normal macports python. I also get the same error message trying to import Tkinter in python/ipython.
